Question
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.

find the mass of the puck when the length of the string is 2.0 m, string tension is 8.0 N, and the tangential speed of the puck is 1.0 m/s.
