The only force acting on a 1.0 kg canister that is moving in an xy plane has a magnitude of 4.1 N. The canister initially has a velocity of 3.9 m/s in the positive x direction, and some time later has a velocity of 7.9 m/s in the positive y direction. How much work is done on the canister by the 4.1 N force during this time?
