Question

a car of mass 1000 kg starting from rest and moving with uniform acceleration covers a distance of 20m in 2 sec . calculate the work done

Answer 1

work done=force*displacement
                 =(1000*10)*20
                     10000*20
                         200000j

Answer 2

work done here will be,
as we know that we have a formula t calculate work done
i.e.,w.d=f*s(force *displacement)
here,it is clearly given that
            =(1000*10)*20
            =10000*20
            =200000joules
