1. on a frictionless horizontal air track car a mass 0.25 KG is moving towards cart be mass 0.75 KG, which is initially at rest.After the collision cart a has a velocity of 0.15 MS to the left and Kaur-B has a velocity of 0.50 MS to the right.A. What was the speed of Carré before the collision and in what direction wasn't moving?B. What is the collision elastic prove your answer?2. A train travels between stations 2.72 KM apart along a straight line the train starts from rest at the First Station and doesnot need to stop at the second station passing it at a speed of 100 KM/hrA. What is the speed of the train at the second station?B. What is the acceleration of the train between stations assuming that it is constant in m/s2C. How long does the train take to travel between the two stations?
