Two blocks, each of mass m = 6.90 kg , are connected by a massless rope...
Two blocks, each of mass m = 6.90 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 = 2.90 m from block A's initial position the slope becomes frictionless. What is the velocity of the blocks 4.10 s after the blocks have started moving? Assume...

Two astronauts of roughly equal mass are floating in space. They both hold onto a light rod 20 m long, and the whole system is rotating about the center of the rod about once every 30 s. a) What is the tangential speed of each astronaut? b) Now imagine the astronauts pull themselves along the rod until they are 10 m apart. What is their tangential speed now? c) Where do you think that their increased kinetic energy came from?
