- A fuel-powered loader raises a 2.2 x 103-kg load from the ground to a loading platform, which is 2.7 m above the ground. Theloader consumes 1.5 X 105 J of energy from the fuel while raising the load. (a) Determine the work done by the loader on theload. (b) Calculate the efficiency of the loader.Problem 2: Suppose a car approaches a hill and has an initial speed of 108 km/h at the bottom of the hill. The driver takes her foot off of the gas pedal and allows the car to coast up the hill. a) If the car has the initial speed stated at a height of h = 0, how high, in meters, can the car coast up a hill if work done by friction is negligible? b) If, in actuality, a 770-kg car with an initial speed of 108 km/h is observed to coast up a hill and stops at a height 20.5m above its starting point, how much thermal energy was generated by friction in J?A 3500 lb SUV is traveling at 30 mph up a 6% slope when the engine quits. Use work and energy to determine the distance traveled until the vehicle comes to rest (at which point the parking brake is applied). Assume drag forces are negligible.
