1.a car sitting at rest on the road
balanced or unbalanced
explain your answer
Answer:
Balanced force
Explanation:
Balanced Forces, When forces are in balance, acceleration is zero. Velocity is constant and there is no net or unbalanced force. ... Although friction is acting on the person, there is no change in velocity and friction is not a net force in this case. Friction is only a net force if it changes the velocity of a mass.
The car is balanced.
If there are any forced acting on it, then those are balanced too.

how much time is required for an airplane to reach its takeoff speed of 77m/s if it starts from rest to average acceleration is 8.2 m/s
Answer:
t = 9.36 s
Explanation:
Given that,
Initial velocity, u = 0 (at rest)
Final velocity, v = 77 m/s
Acceleration of the airplane, a = 8.2 m/s²
We need to find the time required for an airplane to take off its speed 77 m/s. Let t be the time. using first equation of motion to find it as follows :
v=u+at
[tex]t=\dfrac{v-u}{a}\\\\t=\dfrac{77}{8.22}\\\\t=9.36\ s[/tex]
so, the airplane will take 9.36 seconds.

A rock falls from rest off a high cliff. How far has the rock fallen when its speed is 39.2 meters per second?
( plss I need help lol)
The rock fell as far as 78.4 meters.
Given the following data:
Initial speed = 0 m/s (since the rock fell from rest). Final speed = 39.2 m/sWe know that the acceleration due to gravity (a) for an object is equal to 9.8 meter per seconds square.
To find how far (distance) has the rock fallen, we would use the third equation of motion;
[tex]V^2 = U^2 + 2aS[/tex]
Where:
V is the final speed. U is the initial speed. a is the acceleration. S is the distance covered.Substituting the given parameters into the formula, we have;
[tex]39.2^2 = 0^2 + 2(9.8)S\\\\1536.64 = 0 + 19.6S\\\\19.6S = 1536.64\\\\S = \frac{1536.64}{19.6}[/tex]
Distance, S = 78.4 meters.
Therefore, the rock fell as far as 78.4 meters.

Se lanza una piedra de 3.00 N verticalmente hacia arriba desde el suelo. Se observa que, cuando está 15.0 m sobre el suelo, viaja a 25.0 m/s hacia arriba. Use el teorema trabajo-energía para determinar a) su rapidez en el momento de ser lanzada. b) su altura máxima
Answer:
(a). The speed at the moment of being thrown is 30.41 m/s.
(b). The maximum height is 47.18 m.
Explanation:
Given that,
Weight of stone = 3.00 N
Height = 15 m
Speed = 25.0 m/s
(a). We need to calculate the speed at the moment of being thrown
Using work energy theorem
[tex]W=\dfrac{1}{2}m(v_{2}^2-v_{1}^2)[/tex]
[tex]-mg\times d=\dfrac{1}{2}m(v_{2}^2-v_{1}^2)[/tex]
Put the value into the formula
[tex]-9.8\times15=\dfrac{1}{2}\times(v_{2}^2-v_{1}^2)[/tex]
[tex]-2\times9.8\times15=25^2-v_{1}^2[/tex]
[tex]-v_{1}^2=-300-25^2[/tex]
[tex]v_{1}=\sqrt{925}[/tex]
[tex]v_{1}=30.41\ m/s[/tex]
(b). We need to calculate the maximum height
Using work energy theorem
[tex][tex]W=\dfrac{1}{2}mv_{2}^2-\dfrac{1}{2}mv_{1}^2[/tex]
[tex]mg\times d=\dfrac{1}{2}mv_{2}^2-\dfrac{1}{2}mv_{1}^2[/tex]
Here, [tex]\dfrac{1}{2}mv_{2}^2[/tex]=0
[tex]-(mg)\times d=\dfrac{1}{2}mv_{1}^2[/tex]
[tex]d=\dfrac{v_{1}^2}{2g}[/tex]
Put the value into the formula
[tex]d=\dfrac{30.41^2}{2\times9.8}[/tex]
[tex]d=47.18\ m[/tex]
Hence, (a). The speed at the moment of being thrown is 30.41 m/s.
(b). The maximum height is 47.18 m.

Billy, a mountain goat, is rock climbing on his favorite slope one sunny spring
morning when a rock comes hurtling toward him from a ledge 40.0 m above.
Billy ducks and avoids injury. a) How fast is the rock traveling when it passes
Billy? b) How does this speed compare to that of a car traveling down the
highway at the speed limit of 25 m/s (equivalent to 55 mi/h)?
Answer:
There is not enough information to solve how fast the rock was traveling
They are both very fast, as mountain goats are very fast, and if he ducks, he was faster than the rock. The speed compares
Explanation:
I did find this tho.
This question can be solved by using the law of conservation of energy.
a) The rock is traveling at "28 m/s" when it passes billy.
b) The speed of the rock is "1.12 times" the speed of the car.
a)
We can find the speed of the rock by using the law of conservation of energy:
Loss of Potential Energy = Gain in Kinetic Energy
[tex]mgh = \frac{1}{2}mv^2\\\\2gh = v^2\\v = \sqrt{2gh} \\\\[/tex]
where,
v = speed of the rock = ?
g = acceleration due to gravity = 9.81 m/s²
h = height = 40 m
Therefore,
[tex]v = \sqrt{2(9.81\ m/s^2)(40\ m)}[/tex]
v = 28 m/s
b)
Now, we find the ratio between the speed of the rock and the speed of the car:
[tex]\frac{speed\ of\ rock}{speed\ of\ car} = \frac{28\ m/s}{25\ m/s}\\\\speed\ of\ rock = (1.12)speed\ of\ car[/tex]

How many hours would it take a plane to fly 1,500 miles if it was moving at a constant speed of 400 miles/hour.
It would take 3 hours and 45 minutes, for a plane to fly 1,500 miles if it was moving at a constant speed of 400 miles/hour.
Calculation
Round off 3.75 to the nearest one to give the hour value i.e., 3.The minutes are obtained by multiplying the fractional portion of the decimal value by 60, or 0.75 x 60 = 45.we have 3 hours and 45 minutes.What is speed?The distance traveled in a unit of time is called speed. It refers to a thing's rate of movement.This scalar quantity known as speed is the velocity vector's magnitude, It has no clear direction.A faster rate of movement is indicated by a higher speed. It is travelling more slowly if the speed is lower. It has zero speed if it isn't moving at all.The formula: can be used to determine the constant velocity of an object traveling straight forward.r = d / twhere,
r stands for rate or speed (sometimes denoted as v, for velocity)
d is the traveled distance.
t is the amount of time needed to finish the movement.
The average speed of an object over a period of time is given by this equation. We can see the object's average speed here, however at some moments over the time frame, it may have been moving faster or slower.As the time interval gets closer to zero, the maximum average speed is reached. The speed at that moment is what you see when you look at a speedometer in an automobile. While you may have briefly reached a speed of 60 mph, your average speed over the course of 10 minutes could have been much higher or much lower.M/s is the SI unit of speed (meters per second). Miles per hour or kilometers per hour are the most widely used units of speed in everyday life. A typical speed at sea is in knots, or nautical miles per hour.To learn more about speed, refer to https://brainly.com/question/24739297

is an atom with one valence electron more reactive than an atom with two electrone?
Answer:
An atom with a closed shell of valence electrons (corresponding to an electron configuration s2p6) tends to be chemically inert. An atom with one or two valence electrons more than a closed shell is highly reactive, because the extra valence electrons are easily removed to form a positive ion.Explanation:
A car is initially moving at 10.5 m/s and accelerates uniformly to reach a speed of 21.7 m/s in 4.34 s. How far did the car move during this acceleration?
A. 69.9m
B. 6.99m
C. 69.6m/s
D. 6.99m/s
Answer:
A. 69.9m
Explanation:
Given parameters:
Initial velocity = 10.5m/s
Final velocity = 21.7m/s
Time = 4.34s
Unknown:
Distance traveled = ?
Solution:
Let us first find the acceleration of the car;
Acceleration = [tex]\frac{v - u}{t}[/tex]
v is final velocity
u is initial velocity
t is the time
Acceleration = [tex]\frac{21.7 - 10.5}{4.34}[/tex] = 2.58m/s²
Distance traveled;
V² = U² + 2aS
21.7² = 10.5² + 2 x 2.58 x S
360.64 = 2 x 2.58 x S
S = 69.9m
