<A ball is thrown vertically upward. What are its velocity and acceleration when it reaches its maximum altitude?
At the maximum altitude the ball stops so what are its (instanteous) velocity and acceleration?
What is its acceleration just before it hits the ground? > What is the acceleration of any object falling under the force of gravity?
