A system consists of two masses mi = 2.00 kg and m2 = 7.00 kg connected by a massless and a man y unstretchable cable over a massless and frictionless pulley. See the figure below. Assume the ramp is frictionless and 0 = 38.3 . The blocks start from rest and move a distance L = 12.0m. @ bra lolly and fa medeye enl nto vlivana vd snob how What is the work done by normal force on the system Igelb s at the end of the displacement L? m
