Question

A train starting from a railway station and moving with uniform acceleration attains a speed 20m/s in 10 seconds. find its acceleration.​

Answer 1

Here, t = 10 seconds

u = 0 m/s (assuming that train starts from rest)

v = 20 m/s

So, a = (v-u)/t = (20-0)/10 = 2 m/s^2.

Answer 2

Explanation:

a= Vf -Vi

t

a= 20-0

10

a= 2 meter per second square
