Q1. In a skating stunt called 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 70.0 kg and is 6.35 m from the pivot. He is skating at a speed of 7.50 m/s. find out the magnitude of the centripetal force that acts on him.

Q2. A uniform steel beam has a mass of 1640 kg. On it is resting half of an identical beam. What is the vertical support force at each end?
