Example Question #181 :Newtonian Mechanics And Motion

A child throws a ball straight up into the air. He throws the ball with an initial velocity of. Assume there is no air resistance.

What is the vertical acceleration of the ball when it is at its peak height?

Possible Answers:

Correct answer:

Explanation:

At its peak height, the ball will have a velocity of; however, the acceleration on the ball due to gravity is constantly experienced by the baseball. As a result, while in the air, the ball will always have a vertical acceleration of

Example Question #182 :Newtonian Mechanics And Motion

A ball is thrown straight up into the air. When the ball is at the top of its flight, what is its acceleration?

Possible Answers:

It depends on the initial velocity of the ball

Correct answer:

Explanation:

Near the earth's surface (neglecting air resistance), all objects in free-fall accelerate downwards at. This occurs even when the object's velocity is zero, for example when it is at the top of its flight.
