Question

a train starts from rest and accelerates uniformly at the rate of 5 metre per second square for 5 seconds calculate the velocity of train in 5 seconds

Answer 1

Since train starts from rest the initial velocity is 0m/s

We know that
a = v - u/t
Here , u = 0 m/s
a = 5 m/s^2
t = 5 s
v = ?

5 = v - 0/5
25 = v

v= 25 m/s

Hope This Helps You!

Answer 2

Initial velocity of the train(u) = 0 m/s as it starts from rest.

Acceleration given(a) = 5 m/s²

Time given(t) = 5 seconds

We have to calculate final velocity(v)

Then by Newton's First equation of motion

v= u + at

v= 0 + 5×5

v= 25 m/s
