Answer:

50 s

Explanation:

Given:

Δx = 0.005 m

v₀ = 0 m/s

t = 0.50 s

Find: a

Δx = v₀ t + ½ at²

0.005 m = (0 m/s) (0.50 s) + ½ a (0.50 s)²

a = 0.04 m/s²

Given:

Δx = 50 m

v₀ = 0 m/s

a = 0.04 m/s²

Find: t

Δx = v₀ t + ½ at²

50 m = (0 m/s) t + ½ (0.04 m/s²) t²

t = 50 s

The answer (distance) is:

The distance of the truck in the given time is 216 m.

Displacement (s) of an object equals, velocity (u) times time (t), plus ½ times acceleration (a) times time squared (t2). Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth's gravitational force as the acceleration rate of an object.

Multiply the acceleration by time to obtain the velocity change: velocity change = 6.95 * 4 = 27.8 m/s . Since the initial velocity was zero, the final velocity is equal to the change in speed. You can convert units to km/h by multiplying the result by 3.6: 27.8 * 3.6 ≈ 100 km/h.

Answer:

The acceleration is a = 2.75 [m/s^2]

Explanation:

In order to solve this problem we must use kinematics equations.

[tex]v_{f} = v_{i} + a*t\\[/tex]

where:

Vf = final velocity = 13 [m/s]

Vi = initial velocity = 2 [m/s]

a = acceleration [m/s^2]

t = time = 4 [s]

Now replacing:

13 = 2 + (4*a)

(13 - 2) = 4*a

a = 2.75 [m/s^2]

Answer:

C

Explanation:

Potential energy is energy that something has when its not moving. Kinetic energy is energy in motion. A ball held over a persons head isn't moving, meanwhile a ball in motion is using kinetic energy.

C)A ball held over a person's head | a ball rolling on the floor.

Objects may have each kinetic electricity and capacity electricity at an equal time. An item may be accelerated above the ground (have capacity electricity) and be shifting at the identical time (and now have kinetic electricity). A baseball, a plane, and a flying chicken are all easy examples of this.

A rushing bullet, a walking person, and electromagnetic radiation like mild all have kinetic energy. Some other example of kinetic strength is the strength associated with the constant, random bouncing of atoms or molecules.

6.7*10^8 mi/hr

Answer:

Your answer is correct, Option B

Answer:

D) 100 kilometres/hour.

Explanation :

Given -

To find -

Solution -

★ Velocity = displacement/time

→ V = 200/2

→ v = 100 km/h

Therefore, the average velocity of the car is 100 km/h.

Answer:Explanation:

If the same strength force is exerted on two objects, but the objects have the different masses, the object with less mass will have a greater change in velocity. ... Forces affect motion because they can change an objects motion.

The reason for two objects being impacted differently even a similar strength of the force is applied/exerted to them:

- Two objects might be affected differently on the application of a force of the same strength owing to the difference in their masses.

Answer: Explanation:

Carbonated drinks are mixtures of water, sugar, flavorings, and dissolved carbon dioxide gas. They are homogeneous because the ingredients are mixed together to form a consistent liquid.

Answer:

10.21m/s²

Explanation:

Radial acceleration, also known as centripetal acceleration, refers to the acceleration of an object along the circular radius. It can be calculated using the formula:

a(r) = v²/r

Where a(r) = radial acceleration

v = velocity

r = radius of the circular path

According to the information provided in the question, velocity (v) = 17.5m/s, radius = 30m. Hence;

a(r) = v²/r

a(r) = 17.5²/30

a(r) = 10.208333

a(r) = 10.21m/s²

Answer:

Explanation:

the cells need oxygen for metabolism, which also creates carbon dioxide as a waste product. The red blood cells then pick up the carbon dioxide and transport it back to the lung. There we exhale it when we breathe out. Red blood cells can also pick up or release hydrogen and nitrogen.

Answer:

Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers. Waves caused by the gravitational pull of the moon and the sun are called tides.

Explanation:

Answer:

Waves are created by energy passing through water, causing it to move in a circular motion. However, water does not actually travel in waves. Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin. Waves are most commonly caused by wind.

Answer:

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]KE = \frac{1}{2} m {v}^{2} \\ [/tex]

where

m is the mass

v is the velocity

From the question

m = 80 g = 0.08 kg

v = 15 m/s

We have

[tex]KE = \frac{1}{2} \times 0.08 \times {15}^{2} \\ = 0.04 \times 225[/tex]

Answer:

y = 15.61 [m]

Explanation:

To solve this problem we must use the following kinematics equation. We must bear in mind that the acceleration of gravity is negative since the direction of gravity is opposite to the direction of motion.

[tex]v_{f} ^{2} = v_{i} ^{2} -(2*g*y)[/tex]

where:

Vf = final velocity = 0

Vi = initial velocity = 17.5 [m/s]

g = gravity acceleration = 9.81 [m/s^2]

y = height [m]

The final speed is zero, since the ball reaches the maximum height its speed will be zero since it cannot be lifted up more.

0 = (17.5)^2 - (2*9.81*y)

306.25 = 2*9.81*y

y = 15.61 [m]
