Question

Consider the path of a ball moving along a path through the air under the action of the gravitational force.
(Neglect the effect of air friction). As its reaches the highest point in its trajectory, which of the following
statements is true.
(A) The magnitudes of the velocity and acceleration are zero.
(B)The magnitude of velocity is minimum but not equal to zero.
(C) The magnitude of velocity is equal to zero, and the magnitude of the acceleration is constant and not
equal to zero.
(D)The magnitude of the velocity is at a minimum but not equal to zero and the magnitude of acceleration is
Zero,​

Answer 1

Answer: C

Explanation: When ball is moving due to gravitational force, acceleration is acceleration due to gravity. Therefore acceleration is constant and not zero.
