Question

If a train 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

0.706 m/s/s because acceleration equals velocity over time

Answer 2

Answer:0.71m/s^2

Explanation:

But we have to convert 1minute 25seconds to seconds.

Since 60seconds=1minute 1minute 25seconds=85seconds

Acceleration=(final velocity-initial velocity)÷time

Acceleration=(0-60)÷85

Acceleration=-60/85

Acceleration=-0.71m/s^2

The minus sign indicate that the car is decelerating
