Any help with this test prep question would be greatly appreciated.
A block of mass M = 2.0 kg accelerates to the right on a surface with a kinetic coefficient of friction of MU_k = 0.30 pulled by a massless string which passes over a massless and frictionless pulley as shown. A block of mass m = 1.0 kg hangs freely from the other end of the string. Call the tension in the string T and the frictional force F_F. Draw a free body diagram for each of the blocks. Be sure to label all forces, including T and F_F. Block M: Block m: Write an algebraic relation expressing Newton’s second law in the x-direction (horizontal) and y-direction (vertical) for block M and in the y-direction (vertical) for block m. Block M: Block m: Use substitution to algebraically eliminate the tension T from these two expressions and solve for the acceleration of the blocks.
