Collision the engineer of a passenger train traveling at 25.0 m/s sights a freight train whose caboose is 200 m ahead on the same track (Fig. 2.47). The freight train is traveling at 15.0 m/s in the same direction as the passenger train. The engineer of the passenger train immediately applies the brakes, causing a constant acceleration of -0.100 m/s2, while the freight train continues with constant speed. Take x = 0 at the location of the front of the passenger train when the engineer applies the brakes.
(a) Will the cows nearby witness a collision?
(b) If so, where will it take place?
(c) On a single graph, sketch the positions of the front of the passenger train and the back of the freight train.
