A train is travelling along a straight horizontal track and its speed as it passes a signal box A is 5 ms l. Immediately after passing A the train accelerates at a rate of 0-6ms 2 for 25 s; it then travels at a constant speed of V ms I before it finally decelerates uniformly for 30 s, coming to rest at station B. The train then decelerates uniformly at 1 4 The brakes are applied and the train decelerates uniformly to rest in a time of 40 s. (a) suppose rain falls vertically into an open cart rolling along a straight horizontal track with no friction. For a day, it can be used. Plan: 1. The student throws a ball into the air along a path that he judges to make an initial angle of 60.0 with the horizontal and to be in line with the track.
