Q. A bowling ball (mass = 5.0 kg, radius = 0.11 m) and a billiard ball (mass = 0.40 kg, radius = 0.028 m) may each be treated as uniform spheres. What is the magnitude of the maximum gravitational force that each can exert on the other?
Q. A banked circular highway curve is designed for traffic moving at 64 km/h. The radius of the curve is 199 m. Traffic is moving along the highway at 46 km/h on a rainy day. What is the minimum coefficient of friction between tires and road that will allow cars to negotiate the turn without sliding off the road?
