#Horizontal component of 100m/s=100 sin60=50×(root 3)=50×1.732=86.6m/s
#Vertical component of 100m/s=100 cos 60°=100/2=50m/s
(¡) Maximum height it can reach=(v^2+u^2) /2a=0+(50^2) / 2×(-10)=125m
(¡¡) The time takes to reach the maximum height =2S/(u-v)=125×2/(50-0)=5s
(¡¡¡) Horizontal range=ut=86.6×5=433m
Explanation:
# At the highest point (vertical) velocity is zero
#Velocity (horizontal) remains constant
(¡)By v^2=u^2+2as equation
(¡¡)By S=1/2(u+v)t equation
(¡¡¡) S=ut therefore horizontal range=ut

The combined mass of a race car and its driver is 600 kg. Travelling at constant speed, the car completes one lap around a circular track of radius 160 m in total time of 36 s. What is the magnitude of the centripetal acceleration of the car?
Answer:
4.88m/s²
Explanation:
Given parameters:
Mass of the race car and driver = 600kg
Radius of path = 160m
time taken = 36s
Unknown:
Centripetal acceleration = ?
Solution:
The centripetal acceleration is the change in velocity of a body along a circular path with time.
It is mathematically expressed as;
a = [tex]\frac{v^{2} }{r}[/tex]
v is the velocity
r = radius of path
v = [tex]\frac{2\pi r}{t}[/tex]
t is the time;
Insert the parameters and solve for the velocity;
v = [tex]\frac{2 x \pi x 160}{36}[/tex] = 27.9m/s
Now,
acceleration = [tex]\frac{27.9^{2} }{160}[/tex] = 4.88m/s²
The magnitude of the centripetal acceleration of the car is [tex]4.87 \;\rm m/s^{2}[/tex].
Given data:
The combined mass of race car and its driver is, m = 600 kg.
The radius of the circular track is, r = 160 m.
The time taken to cover one lap is, t = 36 s.
The velocity of the car while covering one complete lap of circular track is given as,
[tex]v = \dfrac{2 \pi r}{t}\\\\v = \dfrac{2 \pi \times 160}{36}\\\\v = 27.92 \;\rm m/s[/tex]
And the expression for the magnitude of centripetal acceleration is given as,
[tex]a=\dfrac{v^{2}}{r}\\\\a=\dfrac{27.92^{2}}{160}\\\\a=4.87 \;\rm m/s^{2}[/tex]
Thus, we can conclude that the magnitude of the centripetal acceleration of the car is [tex]4.87 \;\rm m/s^{2}[/tex].

where is the centripetal force directed on a banked curve?
Answer:
The net force on a car traveling around a curve is the centripetal force, Fc = m v2 / r, directed toward the center of the curve.
Explanation:LET ME KNOW IF ITS WRONG. HAVE A NICE DAY!!!!!!!!!!
Answer: The net force on a car traveling around a curve is the centripetal force, Fc = m v2 / r, directed toward the center of the curve. The centripetal force is directed at right angles to the motion and also along the radius towards the centre of the circular path. In order for a car to move around a circular track, something must provide a centipetal force. One source of the centripetal force is friction between the tires and the road. This means that the tires do not need to supply any friction at all to keep the car from slipping sideways. ...

A skater of mass 60 kg has an initial velocity of 12 m/s. He slides on ice where the frictional force is 36 N. How far will the skater slide before he stops?
Answer:
d = 120 [m]
Explanation:
In order to solve this problem, we must use the theorem of work and energy conservation. Where the energy in the final state (when the skater stops) is equal to the sum of the mechanical energy in the initial state plus the work done on the skater in the initial state.
The mechanical energy is equal to the sum of the potential energy plus the kinetic energy. As the track is horizontal there is no unevenness, in this way, there is no potential energy.
E₁ + W₁₋₂ = E₂
where:
E₁ = mechanical energy in the initial state [J] (units of Joules)
W₁₋₂ = work done between the states 1 and 2 [J]
E₂ = mechanical energy in the final state = 0
E₁ = Ek = kinetic energy [J]
E₁ = 0.5*m*v²
where:
m = mass = 60 [kg]
v = initial velocity = 12 [m/s]
Now, the work done is given by the product of the friction force by the distance. In this case, the work is negative because the friction force is acting in opposite direction to the movement of the skater.
W₁₋₂ = -f*d
where:
f = friction force = 36 [N]
d = distance [m]
Now we have:
0.5*m*v² - (f*d) = 0
0.5*60*(12)² - (36*d) = 0
4320 = 36*d
d = 120 [m]

What is the net force required to accelerate a 1.1 kg box at a rate of 2.8
m/s??
Answer:
Fnet = 13.86N
Explanation:
Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.
Mathematically, net force is given by the formula;
[tex] Fnet = Fapp + Fg[/tex]
Where;
Fnet is the net force Fapp is the applied forceFg is the force due to gravitationGiven the following data;
Mass = 1.1kg
Acceleration = 2.8m/s²
To find the applied force;
[tex] Fapp = ma[/tex]
Substituting into the equation, we have;
[tex] Fapp = 1.1 * 2.8[/tex]
Fapp = 3.08N
To find the gravitational force;
We know that acceleration due to gravity, g = 9.8m/s²
[tex] Fg = mg[/tex]
Substituting into the equation;
[tex] Fg = 1.1 * 9.8[/tex]
Fg = 10.78N
To find the net force;
[tex] Fnet = Fapp + Fg[/tex]
Substituting into the equation, we have;
[tex] Fnet = 3.08 + 10.78[/tex]
Fnet = 13.86N
Therefore, the net force required is 13.86N

If mass of the ball is 5kg how to calculate the potential energy?!
The mass of the ball is 5 kg and it is lifted 10 meters above the ground, its potential energy is 490 Joules.
What is Potential Energy?
Potential energy is the energy that an object possesses due to its position or condition. It is the energy that an object has stored within itself, ready to be converted into other forms of energy.
To calculate the potential energy of an object, we need to know its mass, the acceleration due to gravity, and its height above a reference point. The formula for potential energy is:
Potential Energy = Mass x Gravity x Height
where:
Mass is the mass of the object, in kilograms (kg)
Gravity is the acceleration due to gravity, which is approximately 9.8 m/s^2 on Earth
Height is the height of the object above a reference point, in meters (m)
If the mass of the ball is 5 kg, we can calculate its potential energy if we know its height above a reference point. For example, if the ball is lifted 10 meters above the ground, we can calculate its potential energy as:
Potential Energy = 5 kg x 9.8 m/s^2 x 10 m
Potential Energy = 490 Joules
