Two objects are floating in a region free of other gravitating bodies. The first object has a mass of 1.4x10^15kg and a radius of 19000m. The second object has a mass of 4.9x10^16kg and a radius of 13000m. They initially rest with a distance of 810000m apart.

A) Determine the force acting on each object initially

B) b/c their mutual gravitational attraction, the two objects will drift towards each other and collide. Determine the speed of each at the instant of collision.

One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 30 m/s. The masses of the two objects are 3.0 and 7.6 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is...

One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 24 m/s. The masses of the two objects are 2.3 and 7.1 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is...
