The puck in Figure 10.24 has a mass of 0.120 kg. The distance of the puck from the center of rotation is originally 39.5 cm, and the puck is sliding with a speed of 80.0 cm/s. The string is pulled downward 18.0 cm through the hole in the frictionless table. Determine the work done on the puck. (Suggestion: Consider the change of kinetic energy.)

Block A in the figure below has mass 1.30 kg , and
block B has mass 2.85 kg . The blocks are forced together,
compressing a spring S between them; then the system is
released from rest on a level, frictionless surface. The spring,
which has negligible mass, is not fastened to either block and
drops to the surface after it has expanded. Block B
acquires a speed of 1.20 m/s .
