Problem 15.83 Part A The 12-lb collar B is at rest, and when it is in the position shown the spring is unstretched. Another 1-1b collar A strikes it so that B slides 4 ft on the smooth rod before momentarily stopping. The coefficient of restitution between A and B is e = 0.4. (Figure 1) Determine the velocity of A just after impact measured to the left. Express your answer to three significant figures and include the appropriate units....

9. a. A spring has constant k-5lb./in. Its natural length is 12 inches. What is the work required to compress it to 9 inches? b. A 100 ft. cable weighs 40 lbs. Find the work done in winding the cable onto a winch, if the cable is hanging vertically c. An unknown positive charge q is placed at the origin. The force F (in Newtons) with which this charge repels a unit positive charge is given by F-kq/r, where k...
