1. A mass, M = 200 g, that is attached to a string, moves in ahorizontal circular path with radius r = 0.5 m. If the speed of themass is 2 m/s, what is the centripetal acceleration? What is thetension in the string?
2. How long does it take the mass to complete one revolution? Howmany revolutions does the mass complete in 2 min?
3. A tetherball of mass m = 500 g is suspended from a string oflength L = 1.5 m. The ball revolves in a horizontal circle movingwith constant speed. The rope makes an angle of 300 with thevertical during the motion. Find the speed of the tetherball.
