1. Consider a bouncy ball and a metal cylinder on a 20 degree incline. Everyone knows a regular bouncy ball has a diameter of 2.5 cm and has a mass of 29 g, the cylinder is 5 cm long with a diameter 1 cm. 1. Use the conservation of energy approach to find the length of time the objects in #1 take to roll down a 1.5 m incline at 200 . t =_________________________ and ____________________________    If you could clearly circle the answers I need, that would be great!! Thanks!
