A simple pendulum is made of a small blob of mass m = 3.000 kg attached to the end of an inextensible wire. The angular amplitude of oscillation is 60 = 5.730". @ Macmillan Learning Use g - 9.807 m/s for the gravitational acceleration. What is the magnitude 7 of the tension in the wire when the blob is directly below its point of support? Z
