Question

A high-speed train accelerates at a constant rate in a straight line.

The velocity of the train increases from 30 m/s to 42 m/s in 60 seconds.
Calculate the change in the velocity of the train.

Answer 1

The change in velocity of the train is 12 m/s.

Step-by-step explanation:

To calculate the change in velocity, we subtract the initial velocity from the final velocity. In this case, the initial velocity is 30 m/s and the final velocity is 42 m/s. So the change in velocity is 42 m/s - 30 m/s = 12 m/s.
