bumper car A (ma = 140 kg) with a velocity of 15 km/h hits a another car B (mb = 160 kg) which was immobile before impact. The collision is perfectly elastic and the frictions are considered negligible. Calculate the time at which the dodgems are 2 m apart from each other after the collision.During a squash game, a player hits the ball, of 24 g, which is moving toward him horizontally at 150 km/h. The impact between the racket
