I used PEsp = KE, which I got 16 = (0.5)(0.1)(v^2), and got 17.89, for my linear speed, and got that wrong. I know that once I get my linear speed, I plug that into an equation to get angular speed, but I would like to know how to get this linear speed correct. Thanks!A pinball (solid sphere of mass = 0.1 kg, outer radius = 0.1 m) is cocked back 0.8 m on a spring (k = 50 N/m), and fired onto the pinball machine surface, which is tilted. When the pinball is 2.5 m above its initial location (on the way up), find its linear and angular speeds.
