Gɪᴠᴇɴ :-
- Initial velocity (u) = 10 m/s
- Final velocity (v) = 20 m/s
- Time taken (t) = 4 s
ᴛᴏ ғɪɴᴅ :-
- Acceleration (a)
sᴏʟᴜᴛɪᴏɴ :-
On using first equation of motion , we get,
➭ v = u + at
➭ 20 = 10 + a × 4
➭ 20 - 10 = 4a
➭ 4a = 10
➭ a = 10/4
➭ a = 2.5 m/s²
Hence,
- Acceleration (a) = 2.5 m/s²

Answer:
HERE IS UR ANSWER DEAR,
GIVEN:
initial velocity (u) =10m/s
final velocity (v) =20m/s
time (t) = 4s
TO FIND:
acceleration (a)
FORMULA :
a = (v-u ) / t
SOLUTION:
a = ( 20-10) / 4
a = 10 / 4
a = 2.5 m/s²
