In a skating stunt known as "cracking-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 5.90 m from the pivot. He is skating at a speed of 7.00 m/s. Determine the magnitude of the centripetal force that acts on him

Two skaters of mass 70kg and 60kg are skating towards each other. The 70kg skater is moving east at a velocity of 10m/s, and the 60kg skater is moving 30° west of north at velocity of 13m/s. When they meet, they hold hands and skate together at velocity v. Calculate the magnitude of v. (A) 9.9m/s (B) 3.m/s (C) 11.m/s (D) 5.7m/s
In a childhood game called “Crack the Whip”, children hold hands, form a line, and pivot around one person at the center. Who is most likely to let go first and why? Refer to the centripetal acceleration and the centripetal force formulas to justify your comments where possible.
