Figure :
Given :
- Initial velocity (u) = 0 m/s
- Final velocity (v) = 40 m/s
- Time (t) = 5 seconds
To Find :
- Acceleration = ?
Solution :
➨ v = u + at -----(First equation of motion)
➨ 40 m/s = 0 + a × 5 s
➨ a = 40/5
➨ a = 8 m/s²
Therefore, the acceleration of the body is 8 m/s².

Given :
Initial velocity,u = 0
Final velocity,v = 40m/s
time ,t = 5 sec
Required To Find out :
Acceleration
Formula required :
where ,
v is final velocity
u is initial velocity
a is acceleration produced
t is the time taken
Solution :
hence, the acceleration produced is 8m/s^2
