A railway truck on a level,straight track is initially at rest.The truck is 2 marks given a quick, horizontal push by an engine so that it now rolls along the track. railway truck push from engi 4.3ms The engine is in contact with the truck for a time T= 0.54 s and the initial speed of the truck after the push is 4.3 ms-1, The mass of the truck is 2.2103 kg. Due to the push, a force of magnitude Fis exerted by the engine on the truck. The sketch shows how Fvaries with contact time t. (i Determine the magnitude of the maximum force Fmax exerted by the engine on the truck. iiAfter contact with the enginet=0.54 s)the truck moves a distance 15 m along the track.After travelling this distance the speed of the truck is 2.8 ms-1 Assuming a uniform acceleration, calculate the time it takes the truck to travel 15 m. (iii) Calculate the average rate at which the kinetic energy of the truck is dissipated as it moves along the track. (iv When the speed of the truck is 2.8ms1 it collides with a stationary truck of mass 3.0x103kg.The two trucks move off together with a speed V.Show thatthe speed V=1.2ms-1. (v) Outline the energy transformations that take place during the collision of the two truck
