Your professor has built a motorized bicycle trailer for carrying loads of groceries up to his house. His worst case scenario (i.e., the design condition) is a 20 kg trailer (including batteries and motor) carrying 20 kg of energy drink up Wrenthan Ave., which has a maximum pitch of 20%. Ouch. Cleverly, he has incorporated a force sensor into his trailer hitch, and he uses the sensor out- put, which is a voltage, to control the amount of power that the motor produces. He defines the error as the amount of force on the trailer (i.e., the target is for the motor to provide just enough "push" so that the force on the hitch is zero). His first attempt uses proportional control, Pmotor = Kp · Vgensor

I don't know how to work this problem. For part A, it gives the solutions to be Vf=-7.1m/s in the x-direction + 23.5m/s in the y-direction. For part B it gives the answer to be K=-1.15*10^7 J, which calculates to 11.5 MJ of energy lost.
