**1. Two blocks are connected by a rope that passes over a set of pulleys. One block has a weight of 412N, and the other has a weight of 908N. The rope and the pulleys are massless and there is no friction. a.) What is the acceleration of the lighter block? b.) Suppose that the heavier block is removed and a downward force of 908N is provided by someone pulling on the rope. Find the acceleration of the remaining block. c.) Explain why the aswers in a and b are different.**

**a= m2-m1 / m2+m1 * g**

**For part a, I found the following. a= 908-412 / 908+412 * 9.80 = 3.68m/s. Is this correct. For part b, how would the answer be different from part a if you are applying the same amount of force and pulling it in the same direction. I'm confused.**
