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

a=60÷85
=0.705 m
is my answer

Answer 2

Given :

Speed of train , u = 60 m/s .

Final speed of train , v = 0 m/s .

Time taken to stop the train , t = 1 minute 25 seconds = 85 s .

To Find :

The train's acceleration .

Solution :

We know , by equation of motion .

$v=u+at\\\\a=\dfrac{v-u}{t}\\\\a=\dfrac{0-60}{85}\\\\a=0.71\ m/s^2$
