I’m working on a physics question and need guidance to help me understand better.1.A 50.0 kg rock starting from rest free falls through a distance of 300.0 m with no air resistance. Find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earth’s velocity.
Earth’s mass is 6.0 × 1024 kg. Show all your work, assuming the rock-earth system is closed.2.A 60 kg skateboarder jumps off a 3.0 kg skateboard while moving at 4.0 m/s. The skateboarder comes to an immediate stop but the skateboard continues to move. Find this final velocity. Show all your work. Assume a frictionless, closed system.
