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 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.
