1 kg ball is attached to a vertical rod by two strings. Each string has a length of 2m and the horizontal distance between those two strings is 3m. The ball rotates in a horizontal circle at constant speed. If the the tension in the upper string is 25 N, find the tension in the lower string and the speed of the ball (in m/s).

A penny of mass 3.10 g rests on a small 20.0-g block supported by a spinning disk (Fig. P6.60). The radius is 12 cm The coefficients of friction between block and disk are 0.750 (static) while those for the penny and block are 0.520 (static). What is the maximum rate of rotation in revolutions per minute that the disk can have, without the block or penny sliding on the disk?
