Question

A monkey is jumping up and down on a trampoline. At the very top of his jump, what is true about his velocity and acceleration?

• A. His velocity and acceleration are nonzero
• B. His velocity is zero but acceleration is nonzero
• C. His velocity is nonzero but acceleration is zero
• D. His velocity and acceleration are zero

Answer 1

The correct option is B

His velocity is zero but acceleration is nonzero

At the top of his jump, his velocity becomes zero but the acceleration due to gravity is still pulling the monkey down which will be as usual 9.8m/s²
