2 2 a) What is the definition of linear momentum? 1 The engine of an unpowered train of mass 700 kg is rolling at a constant speed on a level track, as shown in Fig. 2.1. The engine collides with a stationary truck of mass 900 kg, and joins with it. The two train lock together and continue to move at 8 ms-1 after the collision. moving engine mar Cross 10:00 - LOGICA b) Fig. 2.1 Calculate the momentum of engine and truck after and before the collision. 2 Calculate the speed in km/hour of the engine before the collision 162 d) Calculate the kinetic energy of each train before and after the collision
e) 1 Explain why there is a difference in the total kinetic energy of the engine and truck before and after the collision. N Using the principle of conservation of momentum, calculate the speed of the joined engine and truck immediately after the collision. w
