a student pushes a 40 kg lawnmower from rest across a rough surface with a force of 200 N at an angle of 60 degrees below the horizontal. the lawnmower is moved 3 meters. the coefficient of kinetic friction is 0.3.

how much work did the student do on the lawn mower moving it forward 3 meters?

how much work was transfered from the mower to the ground through the friction force?

what is the speed of the lawnmower at the end of the 3 m of motion?
