Question: Three blocks with masses m1 = 25 kg, m2 = 10 kg and m3 = 15 kg are stacked on top of each other as

Three blocks with masses m1 = 25 kg, m2 = 10 kg and m3 = 15 kg are stacked on top of each other as shown below. A fourth mass, m4 = 16 kg, is suspended by a rope that is attached to m1 via an ideal pulley. Assuming that m1 is evenly supported between m2 and m3, what is the normal force provided by the floor on m2? (Note: Answer in units of Newtons.)
