The sphere at P is given a downward 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 three times the weight of the sphere. Then the value of v_(0) will be : (g=pi ^(2) m//s^(2))
