ME360 - Dynamic Systems Prof. Gillespie - Fall 2010 RAT 1 - Due Sept 14, 12:50pm 1AM: Consider a block of mass m sliding down a ramp as shown in the figure below. Assume that the frictional force f is proportional to the relative locity between the ramp and block: f(v) = by, and assume that during the time period under consideration, dW’block is sliding down the ramp. Problem 1 Draw a free body diagram, clearly indicating all forces acting on the block. Problem 2 Which of the following equations could possibly describe the dynamic behavior of the sliding block system? Circle your answer and justify your answer. 1.’b-t-3v=—2 . ii.+bv rfl9S)Yl Problem 3 Suppose that during a different period of time under consideration,

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
