Explanation Given: One revolution every 2 .5 s Mass of each skater = 55.0 kg Arm length of each skater = 0 .80 m Formula Used: Angular speed is defined as the angle of rotation per second. Centripetal force , = m . a c = m ω 2 r Where, ω is the angular velocity . Calculation: Pull on each other provide necessary centripetal force to move in a circle. F = m ω 2 r ω = 2 π 2
