A train has a mass of 5.0E+6 kg and is moving at 60 km/hr. The engineer applies the brakes, which results in a net backward force of 1.5E+6 N on the train. The brakes are held on for 25 s. What is the new speed of the train? How far does it travel during this period?

    When a high-speed passenger train traveling at vP = 158 km/h rounds a bend, the engineer is shocked to see that a locomotive has improperly entered onto the track from a siding and is a distance D = 692 m ahead (see the figure). The locomotive is moving at vL = 30 km/h. The engineer of the passenger train immediately applies the brakes. Assume that an x axis extends in the direction of motion. What must be the constant acceleration...
