ɢɪᴠᴇɴ :-
- Initial velocity (u) = 0 m/s
- Final velocity (v) = 4m/s
- Time taken (t) = 4 seconds
ᴛᴏ ғɪɴᴅ :-
- Acceleration (a)
sᴏʟᴜᴛɪᴏɴ :-
On using 1st equation of motion, we get,.
➨ v = u + at
➨ 4 = 0 + a×4
➨ 4a = 4
➨ a = 4/4
➨ a = 1 m/s²
Hence,
- Acceleration (a) = 1 m/s²

Given,
- A body starts from rest and Travel at 4 m/s (Final Velocity)
- Initial Velocity - 0 m/s ( Because body start from rest)
- Time - 4 Seconds
To Find,
- Acceleration of the Body
Solution :
We know about the First Equation of Motion :
Here,
- v - Final Velocity
- u - Initial Velocity
- t - Time
- a - Acceleration
Now Put the Value in this Equation :
Therefore,
