You have a flywheel consisting of an outer wheel, an axle, and some spokes. It is rotating quite fast, but you've got a heavy block you can use as a brake. To use it, all you have to do is hold it flat against some part of the flywheel (assume that for the spokes you'd hold it so that it pressed down on each spoke as it slides past the bottom of the block... in other words, in call cases assume you are applying the torque correctly). Where would be the best place to "apply the block" if you want to slow down the flywheel the fastest?

A twice-differentiable function, f(x), has a derivative given by f'(x) = (x²-9)g(x), where g(x) < 0 for all values of x. Use this information to answers question #7-10. Show all work and justify your conclusions (up to 5 points each). 7. For what value(s) of x does f(x) have a relative maximum? Justify. 8. For what value(s) of x does f(x) have a relative minimum? Justify. 9. On what interval(s) of x is f(x) increasing? Justify. 10. On what interval(s) of x is f(x) decreasing? Justify. Use the table of values given for a twice-differentiable function shown below to answer questions 11 through 14 (up to 5 points each).
