You pull on a string with a horizontal force of magnitude Fyb = 32 N that is attached to a block of mass mb = 6.5 kg, then to the axle of a solid cylinder of mass mc = 4.0 kg and radius r = 0.4 m, then to a spring of spring constant k = 185 N/m. 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?
You pull on a string with a horizontal force of magnitude Fyb = 44 N that is attached to a block of mass mb = 6.1 kg, then to the axle of a solid cylinder of mass mc = 4.7 kg and radius r = 0.4 m, then to a spring of spring constant k = 135 N/m. This is all done on an inclined plane where there is friction ( μs = 0.61 and μk = 0.34 ), and the incline angle is θ = 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. How far have you pulled the block and cylinder when everything stops? The velocity when it has traveled 44 cm down the plane is 2.030 m/s.

A puck of mass m=180g on a horizontal, frictionless table is connected to a string that passes through a small hole in the table, as shown in the following figure (attached) The puck is set into circular motion of radius R=50cm with a speed vi = 2.2 m/s. If the string is then pulled from the bottom as shown, so that the radius of the circular path is decreased to r=20cm, what is the final speed, vf, of the puck?

A 0.050kg pendulum is hung from the ceiling of a train so that when the train sits motionless on a banked curve which turns to the right with a turn radius of 210m, the pendulum hangs at an angle of 8.0° to the right of a line perpendicular to the ceiling and floor of the train. How fast is the train going around the same curve if the pendulum bob swings 12° to the left of a line running perpendicular to the floor and ceiling?
