2)A 1.2-kg ball hangs from an upside-down L shaped pole secured by bearing at base as shown. The string length is 1.29 m, while pole's arm is 0.75 m. The pole is spinning, causing the ball to revolve around the pole in a horizontal circle with the string remaining taut and making an angle of 42° with the vertical. Calculate (a) the tension of the string, and (b) the speed of ball. (c) How long does the ball take to make one revolution around the pole? 0.75
