Question

If a train is going 60 m/s hits the brakes, and it takes the train 1 minute 25 seconds to stop, what is the train’s acceleration?

Answer 1

Hey there, the answer is .............................. About 0.7 m/sec^2

Acceleration is the change in speed / time

Change in speed is 60 m/sec

Time is 1 minute 25 second. Convert that to seconds.

Divide the change in speed by the time in seconds.

About 0.7 m/sec^2

So the acceleration is - 60 / 85 = - 0.71 m/s^2
