Document Summary
1. (25 points)lwo blocks with masses. rn1 and irt2. are connected by a massless, un stretchable rope as shown below. There is a coefficient of friction ,u1 between the surface arid block 1 and a coefficient of friction /12 between the surface and block 2. At t = 1) block 2 is started with au initial velocity of v0 down the plane: draw the free body diagram for each block, fluid the tension in the striiig and the acceleration of each block. 2. (25 points) a small object of mass m is placed on the frictionless surface. There are two forces, f1 and f, acting on the object that have components only in the . m" direction, given by c1 and fr2t c2(1 ) with c1 and c2 positive and s is the point shown. The object is placed at rest at the point ;t.
