Question

A train's velocity is slowly decreasing as it approaches a station. About 1 km before it reaches the station, several stowaways jump off the train. What happens to the amount of acceleration if the force remains constant? Assume the train is traveling in the positive direction.

Answer 1

Answer:

Increases

Explanation:

From Newton's second law:

F = ma

If F stays the same and m decreases, then a increases.

Therefore, the magnitude of the train's acceleration increases (the acceleration becomes more negative).
