Adam is helping a friend move. They use a ramp to move things into an tall moving truck. A box full of video games of mass 9.6 kg is pushed up the ramp. As the box starts on the ramp, it has an initial speed of 1.44 m/s. You can assume Adam and his friend push with a force 102 N and that the force is parallel to the ramp. The ramp is at an angle of 19.9° with the horizontal. The coefficient of kinetic friction is 0.400, and the ramp is 4.65 m long.
(a) How much heat is generated by the friction between the ramp and box?
(b) what is the speed of the box if it is pushed all the way to the top of the ramp
