kgf.
who ever will give it correctly I will mark it brainliest answer.​

Answer 1

Explanation:

Force =m

t

(v−u)

=m⋅a

Displacement =

2a

(v

2

−u

2

)

Word done (W) = Force × Displacement

=m⋅a⋅

2a

(v

2

−u

)

W =

)

W =

×20×(2500−1600)

=

×20×900

=9000J

Therefore, the work done to attain the final velocity is 9000J
