A frictionless block is tied to a rough block; find tension in cord when they slide.

SEE ATTACHMENT #1 for a diagram showing parameters.

Frictionless block M1 = 3.6 kg, is connected by a cord to block M2 = 7.5 kg. They are placed on a plane which is at angle b= 25 degrees. The coefficient of friction f = .45 between M2 and the plane. Find the tension in the cord as they slide down.
