Unformatted text preview: 86 Chapt. 8 Potential Energy and Mechanical Energy 6. Knowing it will do no harm (or good) you drop your cat Tarquin Superbus from rest from a height y i onto a VERTICAL spring. Tarquin has mass m . The spring is massless and IDEAL (i.e., sans dissipation) with spring constant k and massless platform on the top on which Tarquin lands. The spring is initially at rest with its platform at the springs intrinsic equilibrium position: we define the springs intrinsic equilibrium position to be the y = 0 level. On landing on the spring platform, Tarquin grips it and holds on tight for the rest of the problem. The problem is entirely 1dimensional. a) Qualitatively what is going to happen to Tarquin after he is on the spring for the foreseeable future? b) Using conservation of energy write down an equation relating y i and the postlanding Tarquin parameters velocity v and height y . Tarquin and platform constitute a point particle of course....
