How do I find the tangential speed of a ball going in uniform circular motion, in the problem I'm working on, a 1.3 m long string makes a 48.8 degree angle below the hoizontal. I am confused as to how I find the w to plug into the Vt=rw equation to get the tangential speed. Thanks for your help!

Problem 12: A merry-go-round is a playground ride that consists of a large disk mounted to that it can freely rotate in a horizontal plane. The merry-go-round shown is initially at rest, has a radius R = 1.3 meters, and a mass M = 241 kg. A small boy of mass m = 46 kg runs tangentially to the merry-go-round at a speed of v = 1.8 m/s, and jumps on. Randomized Variables R = 1.3 meters M = 241 kg m = 46 kg v = 1.8 m/s
