find the position at at t=2 and t=0. The difference in those is the displacement.

Work= force times displacement.

So when t=0, x=0.

When t=2, x=-2

displacement= -2-0 = -2m

W=Fd

F=ma=(5)(9.8)=49

W=(49 N)(-2 m)

W= -98 J

Is this correct??

find the third divetive then substute the a in F=ma< and you will get the force then find the destanse moved then

W=F x
