2. In a pendulum, a small mass of 0.5 Kg is suspended by a cord and revolves in a circle of radius r= 0.5 m. The cord makes an angle of 30 degrees with the vertical. (a) Draw the free body diagram. (b) Calculate the Tension in the cord. (c) Calculate the speed and the period (time required for one revolution) (d) Bonus question. In what direction is the acceleration of the ball, and what causes the acceleration? T m r 2. In a pendulum, a small mass of 0.5 Kg is suspended by a cord and revolves in a circle of radius r= 0.5 m.
