I can't figure out part C

Problem 2 Two rigid strings are tied to a 1.0-kg sphere as shown below. The sphere revolves in a horizontal circle about a vertical pole making one revolution in 3.14 sec. L = 1.73 m and 0 = 30. m Figure 5: Problem 2. (a) Draw and label 'all forces acting on the sphere. Indicate direction of the centripetal acceleration. (4pt) (b) What are the radius of the circle, sphere's speed, and the magnitude of the centripetal acceleration? (6pt) (c) Find the tensions in the strings. (10pt) Bonus: What is the angular speed of the rotating sphere (in rad/s and revolutions per minute)? (3pt) Q. Search
