A ball is pushed with a force of 3N for
2s along a frictionless track. The
graph shows the force on the body
against time.How much work is done by the force?

1.5 first find acceleration from vt graph then distance followed by multiplying with force to get work done

From the graph Displacement 2s S =area under graph 1/2×2×0.5=0.5 work done = FS =3×0.5=1.5J
