Determine the work done in terms of the CR during the expansion phase. Express your answer in terms of the variables nnn, THTHT_H, CRCRCR, and gas constant RRR.

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)
