Dear Shivam,

The formula for Work done is:

 W= F.d .Cos(theta)

where , F= Force

D= Displacement 

Cos (thete ) = angle between the displacement and force applied.

And we know F= m.a ;m=mass and a = acceleration 

Total work done = work done is 0-5sec + workdone in 5-10s

Thus you will get total work done = 3 KJ.

Best Of luck
