Extracted text: Example 3.11 If a mass-spring system with an iron ball of weight W=98 net tonnage can be regarded as undamped free vibration and the spring is such that the ball streches it 1.09m (=AC). How many cycle per minute will the system execute? What will its motion be if we pull the ball down from rest by the 0.16m and let it start with zero initial velocity? (Hints: w=mg, g 9.8, k ="/, angular frequency for the oscillation of a spring, o =.
