A mass m = 5.100 kg is suspended from a string of length L = 1.110 m. It revolves in a horizontal circle (see Figure). The tangential speed of the mass is 2.696 m/s. What is the angle theta between the string and the vertical (in degrees)?
My first question is what is tangential speed? Is that the V in the formula
Ac=v^2/r?
But my biggest problem (I think) is that I can't figure out how to draw a FBD for this picture.
Assistance is appreciated.
