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

From Newton's second law, we have: F b = ma, where F b is the braking force, m is the total mass of the train and a is the... View the full answer
