A bucket crane consists of a uniform boom of mass M = 201 kg and length L = 59.81 ft that pivots at a point on the bed of a fixed truck. The truck supports an elevated bucket with a worker inside at the other end of the boom, as shown in the figure. The bucket and the worker together can be modeled as a point mass of weight 201 lb located at the end point of the boom. M Suppose that when the boom makes an angle of 66.1° with the horizontal truck bed, the bucket crane suddenly loses power, causing the bucket and boom to rotate freely toward the ground. Find the magnitude of the angular acceleration a of the system just after the crane loses Take the rotation axis to be at the point where the power. boom pivots on the truck bed. Use g = 9.81 m/s² for the acceleration due to gravity. For unit conversions, assume that 1 m 3.28 ft and 1 lb = 4.45 N. Express your answer to at least two decimal places. rad lel = 0.2177
