- A truck with a mass of 2020 kg and moving with a speed of 17.0 m/s rear-ends a 832 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. vtf= m/svcf= 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)? Yes, since momentum is conserved in a collision with no external forces acting on the colliding objects.No, since there were no forces acting on either the car or the truck during the collision. No, since kinetic energy may not be conserved.Yes, since the collision is inelastic.A single stationary railway car is bumped by a five‑car train moving at 9.3 km/h. The six cars move off together after the collision. Assuming that the masses of all the railway cars are the same, then the speed of the new six‑car train immediately after impact isA 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.
- When two objects collide and one of them is originally at rest, it is possible that both objects will remain at rest after the collision." Do you agree with this assumption? Discuss with reasons.In an elastic collision in which there are no external forces, which of the following is true? Only the total momentum is conserved. Only the kinetic energy is conserved Both the total momentum and kinetic energy are conserved. Both the total momentum and kinetic energy are not conserved.Two freight trains have a complete inelastic collision at a track crossing. Engine 1 has a mass of 1.4 x 10^4 kg and is initially travelling at 45 km/h [N]. Engine 2 has a mass of 1.5 x 10^4 kg and is initially travelling at 53 km/h [W]. Calculate the final velocity.
