Question

A monkey jumps from ground into the air. At the maximum heigtht that it attains, what is true about its instantaneous velocity and acceleration?

• A. Both velocity and acceleration are non-zero
• B. His velocity is zero but acceleration is non-zero
• C. His velocity is non-zero but acceleration is zero
• D. His velocity and acceleration both are zero

Answer 1

The correct option is B

His velocity is zero but acceleration is non-zero

At the maximum height, the monkey comes to rest so its instantaneous velocity becomes zero. But, the acceleration due to gravity is still pulling the monkey down, which is non-zero.
