An engineer was tasked to determine an efficient way toautomatically bring a cargo up a 5.00 [m] high rough incline, withcoefficient of kinetic friction 𝜇𝑘=0.4, without manual labor. Hecame up with a pulley system as shown below. If the incline isoriented at an angle 𝜃=15° from the horizontal, how muchwork is done on a cargo of mass 𝑀=50.0 [kg] by a counteracting mass𝑚=100. [kg], when it reaches half the height of the incline, fromthe ground? What is the speed of the cargo when it reaches half theheight of the incline?
