Eric finds a new hobby collecting old video games. He gets a friend to help him pick up a large number of video games someone found in their old shed. They use a ramp to move things into an unusually tall moving truck. A plastic bin full of video games of mass 9.6 kg is pushed up the ramp. As the bin starts on the ramp, it has an initial speed of 1.42 m/s. You can assume Eric 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 20.3 with the horizontal. The coefficient of kinetic friction is 0.358, and the ramp is 5.85 m long. (a) How much heat is generated by the friction between the ramp and bin? J (b) What is the speed of the bin if it is pushed all the way to the top of the ramp? m/s Eric finds a new hobby collecting old video games.
