String and the pulley

Attached is one problem.

In the system below, the string and the pulley are massless and the coefficient of kinetic friction between m1 and the incline is 0.2. The system is released from rest and accelerates under the weight of m2.

(a) draw a Free Body Diagram for each block .
(b) Write down Newton's 2nd law for each block and use the results to calculate the acceleration of the system and the tension in the strings.
