You pull on a string with a horizontal force of magnitude Fyb = 62 N that is attached to a block of mass mb = 7.2 kg, then to the axle of a solid cylinder of mass mc = 4.5 kg and radius r = 0.5 m, then to a spring of spring constant k = 70 N/m. This is all done on an inclined plane where there is friction ( μs = 0.65 and μk = 0.34 ), and the incline angle is θ = 33 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 164 cm down the plane?

A spring is attached to a block with a mass of 2.33 kg. The block is set on a rough horizonal surface, and you pull horizontally on the other end of the spring, steadily increasing the force. As soon as the spring stretches 0.126 m beyond its equilibrium length, you notice the block starts to move. If the spring constant is 75.8 N/m, what is the coefficient of static friction between the block and the surface?

A block of mass (m = 12 kg) is attached at its top to a string that goes up and loops over a pulley. The end of the string is then attached to a second block of mass (m = 16 kg) that hangs freely. The bottom of the 12 kg block is attached to a spring with spring constant (k = 120 N/m). This spring is then attached to the floor. a) What is the stretch in the spring from its relaxed position? 6) If the spring was detached from the 12 kg block, what would the acceleration of the two blocks be?
