Question

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

Explanation:

Gravity causes objects to accelerate downwards. Normal force acts perpendicular to a surface. Tension is in a stretched - out object like a string. Air resistance opposes the motion of an object through air, causing it to slow down. Here, as the ball is moving through air and slowing down, air resistance is the responsible force.

Answer:

air resistance
