a ball is dropped from the top of a building. it initially moves at 4.0 m/s. after 0.5 seconds, it moves at 3.8 m/s. what force is responsible for the slowing of the ball? air resistance gravity normal tension

Answer

Answer:

A. air resistance

Brief Explanation:

Gravity accelerates the ball downwards. Normal force acts perpendicular to a surface. Tension requires a string - like object. Air resistance opposes motion and can slow the ball.
