Part A Two blocks, each of mass m = 3.80 kg, are connected by a massless rope and start sliding down a slope of incline 0 = 27.0° att = 0.000 s. The slope's top portion is a rough surface whose coefficient of kinetic friction is pa = 0.180. At a distance d = 180 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) AXO vec v = 4.6 m/s

Learning Goal: To apply the principle of linear impulse and momentum to a system of particles. Integrating the equation of motion, as applied to all particles in a system, yields Part A Σm (v: ), +Σ?F, & -Σ m (v:), where m; is the ith particle's mass, V; is the ith particle's velocity, and F, is the external force that acts on the ith particle. This relationship states that the sum of the initial linear momenta, at time t1, and the impulses of all the external forces acting between times t, and t, is equal to the sum of the linear momenta of the system, at time tz. If the system has a mass center, G, the expression becomes Two blocks, each of mass m = 3.80 kg , are connected by a massless rope and start sliding down a slope of incline 0 = 27.0° att = 0.000 s.
