An ice puck of mass m revolves on an icy surface in a circle at speed v at the end of a horizontal string of length L. The tension in the string is T

Write the equation for centripetal force, and substitute the values T and L appropriately. Then with a bit of elementary algebra, rearrange the equation so that it solves for mass.
Express your answer in terms of the variables T, L, and v.
