Hi everyone, my physics final is coming in 3 days , and I really need to have an answer to this exercise , but I'm stuck ! I don't even understand the problem statement HELP ! A typical fastball is thrwon at approximately 90 mph and with a spin rate of 113 rpm (I don't understand what it is).If the distance between the pitcher's point of release and the catcher's glove is 60.5 ft, how many full turns does the ball make between release and catch ? Neglect any effect of gravity or air resistance on the ball's flight ANY GRAPH OR EXPLAINING WOULD BE PRECIOUS !!
