Question

A train starts from rest and accelerate uniformly at the rate of 5 m/s2 for 5 sec. Calculate the velocity of train in 5 sec.

Answer 1

Hey friend,

We know that :

Acceleration = (Final Velocity - Intial Velocity) /Time

a = (v-u)/t

Here, a = 5m/s^2; t = 5 sec; u= 0
Let the final velocity be v

Using formula,

5 = (v-0)5
5 = v/5
25 = v

Therefore, final velocity is 25m.

Thank you!

Answer 2

First we need to check what are given ,here
a=5m/sec2
u=5m/sec
V=?
t=5sec
By putting formulae
V=u+at we get ,25m/sec (and)
