Reference no: EM132512798

A train is travelling at 15.0 m/s [E] along a straight track. Out of the fog, 750 m behind, a fast express train appears going at 45.0 m/s [E]. The express engineer slams on the brakes. With the brakes on the train needs 150 s to stop.

a. What distance does the express train need to stop?

b. What is the acceleration of the express train when braking?

c. Is there a crash? If so, how long after braking does the crash take place? If not, what is the distance of closest approach?
