On an ice rink, two skaters of equal mass grab hands and spin in a mutual circle once every 2.5 s. If we assume their arms are each 0.80 m long and their individual masses are 60.0 kg, how hard are they pulling on one another?

Solution 68GP

Step 1 of 2:

Consider the two ice skaters spin in a mutual circle of radius r and both have same mass m. The time period is T. We are going to find the force on one another.

The mass of one person m = 60 kg

The time period T = 2.5 s

The radius of the circle r = 0.80 m
