Two astronauts, each with a mass of 57 kg, are connected by a 6.4 m massless rope. Initially they are rotating around their center of mass with an angular velocity of 1.9 rad/s. One of the astronauts then pulls on the rope shortening the distance between the two astronauts to 2.6 m. What is angular speed (in rad/s) of the system at this new separation distance between the astronauts? You may model each astronaut as a point particle.

Two blocks, each of mass m = 6.00 kg , are connected by a massless rope and start sliding down a slope of incline θ = 36.0 ∘ at t=0.000 s. The slope's top portion is a rough surface whose coefficient of kinetic friction is μk = 0.300. At a distance d = 1.90 m from block A's initial position the slope becomes frictionless. What is the velocity of the blocks when block A reaches this frictional transition point? Assume...
