Consider the system shown in the diagram. The pulley is a uniform cylinder with mass m3= 1.0kg and radius R=10cm, the other two masses are m1=4.0kg and m2=3.0kg and alpha a=36.9degrees. Assume the rope is massless, there is no slipping of the rope on the pulley, and there is no friction between m1 and the incline.

a.) What is the acceleration of m1 and m2? What is the angular acceleration of the pulley?

b.) If m2 starts fron 50 cm above the ground, how fast is it going when it hits the ground?
