Question

A train starting from rest attains a velocity of 144 km per hour in 10 minutes. Assuming that the acceleration is uniform, find the acceleration.

Answer 1

Answer:

144 kmph = 144×5/18 = 40m/s

10 minutes = 10×60 = 600s

acceleration = (40-0)/600 = 1/15 m/s²

Answer 2

Answer:

1÷15m /second square

Explanation:

u= o m/s

v = 40 m/s

t=600s

a=v-u÷t

a= 40m/s ÷ 600s

a= 1÷15 m/second square
