4) Playing with a question from Achieve. Suppose in (a) () either of these cases the wire breaks. This question is 5 about what happens at the first instant the wire is no longer exerting any tension. a) Find the angular acceleration of the beam. (Is it different between cases a and b?) b) Find the linear acceleration of the tip of the beam at the far rightand compare that to g, the acceleration due to the Earth's gravitational pull. c) Explain how to make sense of your answer in part b
