A 50 kg block is tied to a 100kg block by a horizontal rope. The 100kg block is being pulled by a 500N force that is 20o above the horizontal which in turn pulls the 50 kg block by the horizontal rope in the same direction.
a) If the coefficient of kinetic friction between both blocks and the floor is 0.2, what is the acceleration of the two block system.
b) What is the tension in the rope between the two blocks?
