You pull on a string with a horizontal force of magnitude Fyb = 56 N that is attached to a block of mass mb = 7.7 kg, then to the axle of a solid cylinder of mass mc = 4.4 kg and radius r = 0.4 m, then to a spring of spring constant k = 125 N/m.

Question

You pull on a string with a horizontal force of magnitude Fyb = 56 N that is attached to a block of mass mb = 7.7 kg, then to the axle of a solid cylinder of mass mc = 4.4 kg and radius r = 0.4 m, then to a spring of spring constant k = 125 N/m. This is all done on an inclined plane where there is friction ( μs = 0.65 and μk = 0.31 ), and the incline angle is θ = 29 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. If the speed of the block and cylinder after you have pulled the block and cylinder 44 cm down the plane is 2.030 m/s, then how far have you pulled the block and cylinder when everything stops? 

You pull on a string with a horizontal force of magnitude Fyb = 56 N that is attached to a block of mass mp = 7.7 kg, then to the axle of a solid cylinder of mass mc = 4.4
kg and radiusr = 0.4 m, then to a spring of spring constant k = 125 N/m. This is all done on an inclined plane where there is friction (ug = 0.65 and uk = 0.31 ), and the
incline angle is 0 = 29 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.
