A truck with a mass of 1570 kg and moving with a speed of 17.5 m/s rear-ends a 652 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. (a) Calculate the initial momentum of the truck (in kg m/s). kg m/s (b) Calculate the final velocities (in m/s) for the truck and the car. Vf = m/s Vf = m/s (c) Calculate the total momentum (in kg m/s) of the truck AND the car after the collision. kg m/s (d) Did you expect the results that you got for Part (a) and (c)? O No, since kinetic energy may not be conserved. O Yes, since the collision is inelastic. O No, since there were no forces acting on either the car or the truck during the collision. O Yes, since momentum is conserved in a collision with no external forces acting on the colliding objects.
A 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 and the ball lasts 1.2 ms and the ball leaves with an identical speed but in the opposite direction as the initial velocity. The ball then hits the wall in front, 8 m away and 18 cm below the height of the hit. What is the average force acting on the ball during the impact?
