Question: The sphere at A is given a downward velocity v0 of magnitude 5 m/s and swings in a vertical plane at the end of a rope of length l = 2 m attached to a support at O. Determine the angle u at which the rope will break, knowing that it can withstand a maximum tension equal to twice the weight of the sphere.
