We want to design a wagon system like the one below while filling the kiln with coal at the Coke factory inside Kardemir. In this system, we want the wagon to reach a speed of v= 1 m/s in t=2 seconds. It will then shoot at constant speed. How much engine power is required to tow a wagon with W= 500 kgf under these conditions P=? (Losses will be ignored). (The slope angle of the ramp is α= 25 degrees.)
