(2) A block of mass m = 2kg, slides on a horizontal surface and collides with a spring of force constant 200N/cm. The block compresses the spring 6.16cm from the un-stretched position. Mechanical energy in the amount of 200m) is dissipated due to friction as the block is brought to rest. What was the speed of the block at the instant of collision with the spring? (5-points)

You pull on a string with a horizontal force F = 34 N that is
attached to a block of mass mb = 7.1 kg, then to the axle of a
solid cylinder of mass mc = 5.7 kg and radius r = 0.4 m, then to a
spring of spring constant k = 115 N/m. This is all done on an
inclined plane where there is friction ( Us = 0.6 and k = 0.30 ), and the incline...
