#8.Kinetics of Particles[Conservation Of Energy] [Problem8]

8.The sphere at A is given a downward velocity Vo of magnitude 5m/s and swings in a vertical plane at the end of rope of length l=2m attached to support at an angle theta. Determine the angle theta at which the rope will break, knowing that it can withstand a maximum tension equal to twice the weight of the sphere.
Note:T=2mg is the condition when the rope just tends to break.
Be careful in supposing datum and height below datum is taken-ve and above datum is taken +ve.
