Two basketballs, each of mass 0.62kg and radius0.12 m, are placed on a floor so that they touch each other. Two golf balls, each of mass0.045 kg and radius 22 mm, are placed on a table so that they touch each other.

Part A

What is the ratio of the gravitational force exerted by one basketball on the other to that exerted by one golf ball on the other?

Two balls are placed, one above the other, and dropped from a height of 1.05 m. The bottom ball has a mass which is 6 times the mass of the top ball. They are dropped from rest. When the balls strike the floor, they have a head on, elastic collision with one another. (Assume that the bottom ball strikes the floor, instantly reverses direction, and then collides with the top ball, which is still travelling downward.) How high will the...

You have three balls, each of which is placed at a particular location on the x-axis. Ball 1 has a mass of m, and it is located at x = 0. Ball 2 also has a mass of m, and it is located at x = −a. Ball 3 has a mass of 4m, and our goal is to determine where it is located. We do know that that magnitude of the net gravitational force experienced by ball 1, because...
