A pinball (solid sphere of mass=0.2 kg, outer radius=0.3 m) is cocked back 0.7 m on a spring (k= 50 N/m), and fired onto the pinball machine surface, which is tilted. c) When the pinball is 2.5 m above its initial location (on the way up), find its linear and angular speeds. I got the answers to parts a through c as the following: a) 12.25 J of energy is initially stored in the spring b) 6.24363 is the maximum height the pinball rolls to (above its initial location.) However, I'm having trouble tackling part c..not really sure where to begin. Anything will help. Thank you so much!
