They start at rest with their centers a distance r i apart ( r i > 2 R ). The gravitational attraction between the planets then brings them together, and they collide. What is the speed of each planet just before they collide?

2. An inclined plane makes an angle θ with the horizontal. A spring with unstretched length 0 used to launch a block of mass m up the inclined plane. The spring is compressed until it has a length i and then the block is released from rest. There is a constant frictional force f between the block and the plane. The maximum vertical
