A Jeep tows a 400kg block uip a 45deg incline. The coefficients of friction between the block and the ground are Us=0.5 nad Uk=0.4. The Jeep and driver have a mass of 2000kg. Assuming that the wheels don't slip, what power must the output power of the jeep be to travel up the incline at 15m/s? Assume that the efficiency of the Jeep's power train is 20%. What power input is required to achieve the required output?
