A 2.50 kg box is pulled by a constant force of 16 N that is exerted at an angle 36.9° above the horizontal. The box has moved a distance of 3.00 m along a horizontal surface whose coefficient of kinetic friction is 0.21. (a) What is the total work done on the box? (b) What is the speed of the box at 3.00 m if it is initially at rest?
