Question

An train car of total mass of 13000 kg is pulling into station and slows down with an acceleration of -4.56 m/s2.

Before the train pulls into station 7 stowaways jump off, each stowaways has a mass 66kg. If the braking force remains the same, what will be acceleration of the train once the stowaways jump out of train?

Top Answer
