You pull on a string with a horizontal force of magnitude Fyb = 69 N that is attached to a block of mass m 6 kg, then to the axle of a solid cylinder of mass me = 4.4 kg and radius r = 0.5 m, then to a spring of spring constant k = 115 N/m. This is all done on an inclined plane where there is friction (μs = 0.65 and μk = 0.36), and the incline angle is 0 = 30 degrees. Everything starts at rest, and the spring is unstretched. The block slides down the plane, the cylinder rolls down the plane (without slipping), and the spring stretches. k lllllllll Fyb b 0 Speed First, what is the speed of the block and cylinder after you have pulled the block and cylinder 172 cm down the plane?
