Question

A train moving with velocity of 54 km/h is accelerated so that its velocity becomes 72 km/h in 15s. find the acceleration of the train

Answer 1

Acceleration = velocity / time
To this we have to convert km/h into m/s
54×5/18 =15m/s
72×5/18 = 20m/s
Acceleration = 35/15=2.33333

Answer 2

Acceleration = velocity / time

To this we have to convert km/h into m/s

54×5/18 =15m/s

72×5/18 = 20m/s

Acceleration = 35/15=2.33333
