The figure below shows a thin rod, of length L and negligible mass, that can pivot about one end to rotate in a vertical circle. A heavy ball of mass m is attached to the other end. The rod is pulled aside through an angle θ and released.
(a) What is the speed of the ball at the lowest point if L = 2.40 m, θ = 18.0°, and m = 500 kg?
m/s
