Question

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

Answer 1

Answer:

25m/s

Explanation:

a=5m/s^2

t=5s

u=0

v=u+at

v=5*5

v=25m/s

Hope this helps...... Please follow me.....

Answer 2

u=0

t=5 sec

a= 5m/s^2

v=?

a= (v-u)/t

5=(v-0)/5

5*5=v

V = 25m/s
