Document Content and Description Below
A vertical support rod is fixed at the center of a platform. A light string of length L is attached to the top of the support rod, and the other end of the string is attached to a sphere of mass m, a... s shown above. The platform rotates with an angular speed that can be varied. When the platform rotates with a constant angular speed w (omega), the string makes an angle q (theta) with the rod. (a) The platform rotates with a constant angular speed. Which of the above graphs correctly shows the magnitude of the angular momentum of the platform as a function of time t about a vertical axis at the center of the support rod? Briefly justify your answer. (b) The platform rotates with a constant angular speed. Is the net torque exerted on the platform about its center clockwise, counterclockwise, or zero? Explain your reasoning. (c) As the period of rotation becomes very small, what value does ? approach? Without writing any equations or formulas, justify your answer. (d) A student derives an equation for the squ [Show More]
