21PRACTICE PROBLEM
A small ball (mass m1) is rotating horizontally in a circle on a frictionless table, connected to a hanging mass (mass m2) by a light string passing through a hole in the table's center, as depicted in the diagram below. Determine the speed of the ball in terms of m1, m2, g (acceleration due to gravity ) and r (radius of the circular trajectory).
