A bob of mass = 0.250 is suspended from a fixed point with a massless string of length = 23.0 . You will investigate the motion in which the string traces a conical surface with half-angle = 25.0.
What tangential speed must the bob have so that it moves in a horizontal circle with the string making an angle 25.0 with the vertical?

Are there units which go with these numbers?

I'm sorry avertical = 0 m/s
r = 9.72×10−2 m
Fr of the inward radial force on the bob in the horizontal plane.= 1.14 N
T tension force on string = 2.74 N
