A box of mass 15.0 kg slides (upwards) on a rough sloping plane with an initial speed of 2.00m / s. The pulling force of the box is 120N and is parallel to the inclined plane, which has an angle of inclination of 30 with respect to the horizontal direction. The coefficient of kinetic friction between the gearbox and the ramp is 0.350 and the gearbox slides 6.00m. (a) How much work is produced by the force of gravity in the box? (b) How much work is produced by the force of friction, (c) How much work is produced by the force of 120N on the gearbox? (d) Calculate the total project. (e) What is the speed of the gearbox after it has traveled 6.00m?
