Question

a train starts from a railway station and moving with uniform acceleration attains a speed 40 km/h in 10 minutes. find its acceleration.​

Answer 1

Answer:

Explanation:

Here we will use the First equation of motion that is -:

v=u+at  [v=final velocity, u=initial velocity, a=acceleration, t=time]

GIVEN

u=0 [as the train started, initial velocity must be 0]

v=40 km/h

t= 10/60 hrs

40= 0+a*(10/60)

a= 240 km/hr
