9. The sled is not moving at point A. If all of the sled's potential energy at point A is conserved, what
is its kinetic energy at each of the four points? SHOW work.
Remember:
KE = 1/2mv2
KE = TME - KE

A 300 kg cart is at rest at point A. It then slides down the track and all its energy is conserved.
10. What is its potential energy at point A?

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
