Suppose that you tie a string with negligible mass and with length L around a ball with mass m. You then hold the end of the string and make the ball swing in a circle horizontally with constant speed under your hand so the circular path is parallel to the ground. While doing this, the string makes an angle of 0 with respect to the vertical axis through the center of the circle. a) Derive an expression assuming negligible drag forces for the ball's tangential speed. Show your derivation b) Using your result, discuss which variables this speed depends on. Which quantity or variable is missing and what does this tell us? Provide a paragraph length response.
