Problem
A passenger in a car moving at 20 m/s relative to the ground throws a 0.50 kg ball straight forward at 5.0 m/s relative to the car. Immediately after the throw, determine (i) the ball’s translational kinetic energy according to the passenger and (ii) the ball’s translational kinetic energy according to an observer standing on the ground.
