This is all done on an inclined plane where there is friction ( μs = 0.69 and μk = 0.40 ), and the incline angle is θ = 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.
- First, what is the speed of the block and cylinder after you have pulled the block and cylinder 6 cm down the plane?
- How far have you pulled the block and cylinder when everything stops?
