For a pendulum that starts from rest, the period p depends on the length l of the rod, on gravity 9, on the mass m of the ball and on the initial angle 00 at which the pendulum is started. (i) Use dimensional analysis to determine the functional dependence of p on these four quantities. (ii) For the largest pendulum ever built, the rod is 20m and the ball is 400kg. Assuming that 0.; = 1116 explain how to use a pendulum that ts on your desk to determine the period of this largest pendulum
