Question

a train starts from rest and acceleration uniformly at the rate of 5m/s2 for 5sec calculate the velocity of train in 5 sec

Answer 1

u=0m/sec.
a=5m/sec^2
t=5seconds
v=???
$v = u + at \\ = 0 + 5 \times 5 \\ = 25$
So,Velocity after 5 seconds of the train is 25m/s.

Answer 2

Answer:

$velocity \: = 25 {m}^{2}$
