1. The problem statement, all variables and given/known data A ball(mass 0.500kg) is tied to the end of a string length= 1.02m. The ball is swung in a vertical circle, with speed decreasing on the way up and increasing on the way down. the ball is being swung in a counter clockwise direction. the speed of the ball is 6.0m/s at the middle of the swing(point B) 4.0m/s at the top of the swing(point C) then back down to 6.0m/s at the other middle of the swing(point D) and then 7.5m/s at the bottom of the swing(Point A). these points would all be at 90. to each other with the first middle point being on the right the second middle point being on the left as the ball is being swung counterclockwise. Calculate the Value in N of the net force at point c. What law are you using? 3. The attempt at a solution My problem is I am not sure whether there will be tangential acceleration acting at this point or merely the two side points so I cannot calculate my force yet. I know that there is the force of gravity acting But I am not certain if there will be tangential acceleration. PLEASE HELP I know it is probably pretty obvious but I cant say for sure if their was or not. originally I was certain their was tangential accel = V2/r but my classmate tried to convince me their would not be and now I am really not sure.
