Question

A ball is thrown vertically upward. At the highest point in its path, which of the following statements is correct?

• A. The acceleration is zero and the velocity is pointing up
• B. The velocity is zero and the acceleration is pointing down
• C. The velocity and acceleration are both zero
• D. The acceleration is zero and the velocity is pointing down

Answer 1

The correct option is B

The velocity is zero and the acceleration is pointing down

The acceleration due to gravity is constant throughout the flight of the ball. It's magnitude is g=9.8 m/s², and it is the same at all points that the ball is not in contact with the ground or your hand. It is the velocity that is zero.
