1)Two masses are connected in a pulley system as shown in the figure. Assume both pulleys are frictionless, and also assume that the strings and pulleys are of negligible mass. If M1 = 76 kg and M2 = 7 kg.
A) what is the acceleration of block 1 in the y direction?
B)What is the acceleration of block 2 in the y direction?

2)Two blocks with masses M1 = 2.7 kg and M2 = 9.9 kg are connected with a massless string over two massless and frictionless pulleys, as shown in the Figure. One end of the string is connected to M1 while the other end is fixed. What is the acceleration of mass M2?

3)What downward force on the leftmost rope in the figure below will hold the 265- N block at rest assuming the pulleys are essentially weightless? Notice that there are two different ropes holding up the load.

4)A 32.7- kg block (m1) is on a horizontal surface, connected to a 5.1- kg block (m2) by a massless string as shown in the Figure. The pulley is massless and frictionless. A force of 221.7 N acts on m1 at an angle of 32.3 °. The coefficient of kinetic friction between m1 and the surface is 0.241. Determine the upward acceleration of m2.
