The engineer of a passenger train traveling at 25m/s sights a freight train whose caboose is 200m ahead on the same track. The freight train is traveling at 15m/s in the same direction as the passenger train. The engineer of the passenger train immediately applies the brakes, causing a constant acceleration of -0.1m/s^2, 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.
Please help me start this problem. What equations do I need to find out if the trains collide?
