The only force acting on a 2.9 kg canister that is moving in an xy plane has a magnitude of 7.5 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 5.1 m/s in the positive y direction. how much work is done on the canister by the 7.5 n force during this time?

15.66 J

Explanation:

mass of block

Force magnitude=7.5 N

Initial velocity =

Final velocity=

Initial Kinetic Energy=

=

Final Kinetic Energy=

=

Work Done =Final -Initial Kinetic energy=37.714-22.056=15.66 J
