Question
The sphere at P is given a downward velocity v0 and swings in a vertical plane at the end of a rope of l = 1 m 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 v0 will be: 
/2 m/s
- 2 /3 m/s
- None of these
/2 m/s
/3 m/s
The correct answer is:

A block of mass m = 2 kg is moving with velocity v0 towards a massless unstretched spring of force constant k = 10 N/m. Coefficient of friction between the block and the ground is m = 1/5. Find the maximum value of v0 , so that after pressing the spring the block does not return back but stops there permanently.
