Question

a train starting from a railway station and moving with uniform acceleration attains a speed 40 kilometre per hour in 10 minutes find its acceleration

Answer 1

Changing 40 kmph into mps
$= 40 \times \frac{5}{18} \\ = \frac{200}{18} mps$

Changing 10 mins in secs.
10 minutes = 10×60=600 seconds.

acceleration =
$= \frac{\frac{200}{18} - 0}{600} \\ = \frac{200}{600} \\ = \frac{1}{3} mp {s}^{ - 2}$
