A baseball is thrown vertically into the air; The acceleration of the ball at its highest point is:
Correct answer: C. zero
- A. 2g down
- B. g up
- C. zero
- D. g down
Explanation
At the highest point of the ball's trajectory in a vertical throw:- The ball momentarily comes to rest in the vertical direction, with its velocity becoming zero.- Acceleration is the rate of change of velocity. At this particular moment, when the velocity is zero, there is no change occurring in the velocity.- Therefore, the acceleration of the ball at its highest point is zero.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
