After considerable effort, Wile E. Coyote (SuperGenius) has managed to position his AcmeTM Mobile Large Spherical Projectile Launch Apparatus (really big cannon on wheels) at the top of a hill overlooking the descrt 163 meters below. Our hero travels back down the hill to admire a job well done but, as luck would have it, he forgets to apply the cannon's parking brake. As a result, the cannon begins to roll back down the hill. Assuming that the cannon starts from rest and that all friction forces are neglected: (a) Use the descrt floor as the reference point to calculate the gravitational potential energy of the cannon when it is at rest at the top of the hill. (b) Calculate the speed of the cannon just before it runs over Wile E. Coyote at the bottom of the hill.

AcmeTM Mobile Large Spherical Projectile Launch Apparatus (really big cannon on wheels)
at the top of a hill overlooking the desert 163 meters below. Our hero travels back down the
hill to admire a job well done but, as luck would have it, he forgets to apply the cannon's
parking brake. As a result, the cannon begins to roll back down the hill. Assuming that the
cannon starts from rest and that all friction forces are neglected:
(a) Usc the descrt floor as the reference point to caleulate the gravitational potential energy
of the cannon when it is at rest at the top of the hill.
(b) Calculate the speed of the cannon just before it runs over Wile E. Coyote at the bottom
of the hill.
