1. A pillbox hat is filled with toothpaste until it has a mass of 9.2 kg. An inquisitive engineering student is using a winch and rope to pull it up a ramp 3.2 m with a steady force of 97 N with the rope parallel to the ramp. If the ramp makes a 17° angle with the horizontal and the coefficient of kinetic friction between the ramp and the pillbox hat is 0.35 find how much energy/work: a) is done by gravity? b) is lost due to friction? c) is done by the steady force? d) What is the change in kinetic energy? e) after the 3.2 m what is the speed of the pillbox hat?
