Solve Part C
Part A Two blocks, each of mass m = 120 kg, are connected by a massless rope and start sliding down a slope of incline 0 = 39.0° att= 0.000s. The slope's top portion is a rough surface whose coefficient of kinetic friction is 0.200. At a distance d = 2.40 m from block A's initial position the slope becomes frictionless. (Figure 1)What is the velocity of the blocks when block A reaches this frictional transition point? Assume that the blocks' width is negligible Express your answer numerically in meters per second to four significant figures. ►View Available Hint(s) v=4.724 m/s All attempts used; correct answer displayed Part B Previous Answers How long does it take block A to reach the transition point?
