Question

When a monkey jumps from ground into the air, at the maximum height that it attains, its instantaneous velocity is and acceleration is .

• A. zero
• B. non zero
• C. zero
• D. non zero

Answer 1

Answer: (A), (B)

The correct options are
A zero
B non zero

When the monkey reaches maximum height, then it changes its direction. Hence, at that instant the velocity becomes zero.
The acceleration due to gravity is still pulling the monkey down, which is non-zero.
Hence, at the maximum height, the velocity is zero but the acceleration is non-zero.
