The last stage of a rocket is traveling at a speed of7800 m/s. This last stage is made up of two parts that are clamped together, namely, a rocket case with a mass of 300.0 kg and a payload capsule by a mass of220.0 kg. When the clamp is released, a compressed spring causes the two parts to separate by a relative speed of920.0 m/s. Suppose that all velocities are along the same line.

1. What is the speed of the case after they separate?

2. What is the increase in kinetic energy after they separate?

3. What is the speed of the payload after they separate?

4. What is the total kinetic energy of the two parts before they separate?
