required to hold the 20-kg crate in the equilibrium position
shown. Each spring has an unstretched length of 2 m and a
stiffness of k = 300 N/m.

You pull on a string with a horizontal force of magnitude F = 40 N that is attached to a block of mass m, = 7.5 kg, then to the axle of a solid cylinder of mass m. = 4.8 kg and radius r = 0.4 m, then to a spring of spring constant k = 140 N/m. This is all done on
an inclined plane where there is friction ( 4s = 0.68 and , = 0.31 ), and the incline angle is e = 25 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

First, what is the speed of the block and cylinder after you have pulled the block and cylinder 86 cm down the plane?
The system is released from rest with no slack in the cable and with the spring unstretched. Determine the distances traveled by the
4.5-kg cart before it comes to rest (a) if m approaches zero and (b) if m= 2.8 kg. Assume no mechanical interference and no friction. The
distances is positive if up the incline, negative if down.
