The answer is <span>D: its acceleration is 1.25 meters/second^2.</span>
Answer:
Friction or tension
Explanation:
Friction stops an object from moving in the presence of force
Answer:
if we use gravity that is 9.8m/s then we get the answer 4.42 seconds
Explanation:
lets do it steps by steps, s=u/t +1/2 at square
100=0+1/2×9.8 time square
100=4.9 time square
100/4.9= time square
t= 10×2.21. as sides changed the signs also changed
t=4.42

When ball is thrown vertically upward. As it rises, what happens to its kinetic energy Kinetic energy decreases.
At the highest point, the kinetic energy is zero because all the kinetic energy is converted to potential energy. Therefore the kinetic energy is zero at the highest point. Kinetic energy is the energy that an object possesses due to its motion. Therefore, if an object is thrown straight up, its kinetic energy is zero at its maximum height.
An object thrown vertically upwards will be slowed down by the earth's gravity. Its speed decreases until it reaches a maximum altitude where the speed becomes zero. Gravity then accelerates it downward evenly. If you throw a ball into the air, it will point up, but gravity will slow it down. The ball is slowing down and has zero velocity at the top of its flight.
