Question: two balls each of radius r and mass m swing...

Question details

Two balls, each of radius r and mass m, swing with the same angular velocity on their own independent cords of length L about a common vertical axis, forming 60-degree angles with the horizontal. The length of only one of the cords can be changed by drawing it into the pylon about which the rotation occurs a. Write an equation that could be solved to determine the new cord length required to make the angle between the cord and the horizontal 50 degrees. Assuming that the length change takes place instantaneously, write an expression in terms of I for the time it will take for the balls to pass each other once their cords are different lengths. C. Write an expression in terms of I for the clearance between the two balls as they pass each other. 60°
