a ball of15 kg and 4 cm radio estto suspended at the lower end of an iron wire whose unelongated length is 2.85 my hanging from a point located at a height2.94 m above the floor. The diameter of the wire is0.09 cm and its Young's modulus 180 GPa. The ball is set to oscillate in such a way that its center passes through the lowest point of its trajectory at a speed5 m/yes. Draw the diagram and obtain a formula to calculate the distance d from the floor to passto the ball.
