Acceleration = final velocity - initial velocity/ time
a = v-u/t
t=5
a =5
v=0
5 = v -0/5
v = 25 m/s
a = v-u/t
t=5
a =5
v=0
5 = v -0/5
v = 25 m/s
ShreyaGarg:
please give me answer properly with step by step. I don't understand this answer
acceleration is just rate of change of velocity
since the car starts from rest, the initial velocity is zero.
we need to find the final velocity, so we assumed it to be v variable
time is given as 5 sec and value of acceleration is also given as 5 m/s²
so we just put all these values in the formula and solve for value of v

Answer:-
= 25 m/s.
Given
u=0
a=5m/s ^2
t=5sec.
to find velocity of train, we use v=u+at
⇒v=u+at
⇒ V=0+5*5
⇒ V=25 m/s.
velocity of train in 5 second is 25 m/s.
Explanation:-
The three equations of motion
- v = u + at
- s = ut + (1/2) at²
- v² = u² +2as
