Question

A train starting from a railway station moving with a uniform acceleration attains a speed of of 40 kmh in 10 mins. Find its acceleration

Answer 1

The units have to be in standard form.

40km = 40000m

10 mins = 600 secs

Acceleration = Change in velocity/Time

a = v2 - v1/600

a = 40000/600

a = 66.66 m/s^2
