Question
You pull on a string with a horizontal force of magnitude F = 59 N that is attached to a block of mass m = 6.3 kg, then to the axle of a solid cylinder of mass mc =
5.9 kg and radius r = 0.4 m, then to a spring of spring constant k = 145 N/m. This is all done on an inclined plane where there is friction (μ = 0.63 and μ = 0.36), and
the incline angle is 0 = 28 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.
