t1=0.8728 s Correct You can verify your result by computing this time using the kinematic equations that describe the motion of a particle with constant acceleration: t1=2d/a or t1=v/a Part C What is the velocity of the blocks 4.40 s after the blocks have started moving? Assume that the rope joining the two blocks in long enough so that, at this time, block A is on the frictionless surface while block B is still on the rough surface. (Figure 2). Express your answer numerically in meters per second to three significant figures.
Learning Goal: Integrating the equation of motion, as applied to all particles in a system, yields ∑mi(vi)1+∑∫t1t2Fidt=∑mi(vi)2 where mi is the th particle's mass, vi is the ith particle's velocity, and Fi 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 t1 and t2 is equal to the sum of the linear momenta of the system, at time t2. If the system has a mass center, G, the expression becomes Figure
Two blocks, each of mass m=7.60 kg, are connected by a massless rope and start sliding down a slope of incline θ=40.0∘ at t=0.000 s. The slope's top portion is a rough surface whose coefficient of kinetic friction is μk=0.350. At a distance d=1.40 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.
