A bowling ball (mass = 7.2 kg, radius = 0.12 m) and a billiard ball (mass = 0.31 kg, radius = 0.028 m) may each be treated asuniform spheres. What is the magnitude of the maximum gravitationalforce that each can exert on the other?
1____________ N

When a parachute opens, the air exerts a large drag force on it.This upward force is initially greater than the weight of the skydiver and, thus, slows him down. Suppose the weight of the skydiver is 902 N and the drag force has amagnitude of 1030 N. The mass of the skydiver is 92.0 kg. What are the magnitudeand direction of his acceleration?
magnitude 1__________ m/s2
