A train starting from a railway station and moving with uniform acceleration attains a speed of 40 km/hr in 10 minutes. Find its acceleration

Explanation

final speed=40km/hr, time taken=10minutes

initial speed=0.
we know `Acceleration=a=( v-u)/(time taken)`, where v and u are final and initial velocity

thus `a=(40)/(1/6)`=240km/hr sq.
