Atall, cylindrical chimney falls over when its base is ruptured. treat the chimney as a thin rod of length 53.2 m. at the instant it makes an angle of 34.1° with the vertical as it falls, what are (a) the radial acceleration of the top, and (b) the tangential acceleration of the top. (hint: use energy considerations, not a torque.) (c) at what angle θ is the tangential acceleration equal to g? assume free-fall acceleration to be equal to 9.81 m/s2
