3/213 The two mine cars of equal mass are connected by a rope which is initially slack. Car A is given a shove which imparts to it a velocity of 4 ft/sec with car B initially at rest. When the slack is taken up, the rope suffers a tension impact which imparts a velocity to car B and reduces the velocity of car A. (a) If 40 percent of the kinetic energy of car A is lost during the rope impact, calculate the velocity Ug imparted to car B. (b) Following the initial im- pact, car B overtakes car A and the two are coupled together. Calculate their final common velocity vc- 4 ft/sec B A Problem 3/213 3/213 The two mine cars of equal mass are connected by a rope which is initially slack.
