The sphere at `P` is given a down ward velocity `v_(0)` and swings in a vertical plane at the end of a rope of `l = 1m` attached to a support at `O`. The rope breaks at angle `30^@` from horizontal, knowing that it can withstand a maximum tension equal to four times the weight of the sphere. then the value of `v_(0)` will be `(g = 10 m//s^(2))`.
