A conical pendulum rotates at a horizontal angular velocity of 9.549 rpm. The length of the string is 15 m and the pendulum mass is 21 kg. Determine:
a) The tension in the string.
b) The radius of the turning circle.
c) The centripetal acceleration of the mass. d) The centripetal force of the mass.
Data: g = 9.8 m/s2
