(a) A massless string of length 2? connects two hockey pucks that lie on frictionless ice. A constant horizontal force F is applied to the midpoint of the string, perpendicular to it (see Fig.). How much kinetic energy is lost when the pucks collide, assuming they stick together?(b) The answer you obtained above should be very clean and nice. Find the slick solution (assuming that you solved the problem the ??normal?? way, above) that makes it transparent why the answer is so nice.
