A Velocity is zero, acceleration is zero
B Velocity is zero, acceleration is 9.8 m/s² downwards
C Velocity is maximum, acceleration is zero
D Velocity is zero, acceleration is 9.8 m/s² upwards

Show answer and explanation

Answer: B. Velocity is zero, acceleration is 9.8 m/s² downwards

Answer: B) Velocity is zero, acceleration is 9.8 m/s² downwards
Explanation: When an object reaches its highest point, it momentarily stops moving, so its velocity is 0. However, gravity never stops pulling it downward, meaning the acceleration due to gravity (g ≈ 9.8 m/s²) remains constantly active and directed toward the center of the Earth.
