In a skating stunt known as "crack-the-whip," a number of skaters hold hands and form a straight line. They try to skate so that the line rotates about the skater at one end, who acts as the pivot. The skater farthest out has a mass of 80.0 kg and is 6.10 m from the pivot. He is skating at a speed of 6.80 m/s. Determine the magnitude of the centripetal force that acts on him.© BrainMass Inc. brainmass.com March 4, 2021, 5:46 pm ad1c9bdddf
Centripetal force = m*v^2/r
m = mass = 80.0 kg
r = radius of the circluar ...
With explanations and formulas, the problem is solved.
