Question

A monkey jumps from ground into the air. At the maximum height 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 top of his jump, his instantaneous velocity becomes zero but acceleration due to gravity is still pulling the monkey down, which is non-zero.
