A space station, which has a mass of 275000 kg and is attached to a rocket of mass 200000 kg, is sitting “at rest” in space. The rocket leaves the space station with a velocity of 15000 m/s. What will be the final speed of the space station?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
