3) Bubba is in his pasture one day with his cattle. He has a large cylindrical barrel of cattle feed of diameter 80.4 cm. He pushes the barrel over onto its side to pour the feed out, but the pasture is on a hill. The ground slopes downward at an angle of 12.4 degrees. The barrel rolls a distance of 33.5 meters along the incline. You may treat the barrel as a solid cylinder. a) Determine how fast the barrel is moving at the bottom of the hill. b) Determine the rotational rate of the barrel at the bottom of the hill. :2) Determine how many rotations the barrel went through as it rolled down the hill
