Question

At the maximum height of a body thrown vertically up:

• A. Velocity is not zero but acceleration is zero.
• B. Acceleration is not zero but velocity is zero.
• C. Both acceleration and velocity are zero.
• D. Both acceleration and velocity are not zero.

Answer 1

The correct option is B Acceleration is not zero but velocity is zero.

At the maximum height reached, the body comes to rest and thus its velocity becomes zero while the acceleration due to gravity $(g=9.8m/s^2)$ acting on it continues to act in downward direction and tries to bring the body back to the ground.

Thus at maximum height, the acceleration of the body is non-zero but its velocity is zero.
