A person drops a vertically-oriented, cylindrical steel bar from a height of 4.50 m (measured from the floor to the bottom of the bar). The bar has length = 0.540 m, radius R = 0.750 cm, mass m = 1.300 kg, and Young's modulus Y = 1.000 x 10¹¹ Pa. The bar hits the floor and bounces back up, maintaining its vertical orientation. Use the gravitational acceleration g = 9.81 m/s². Assume that the collision with the floor is elastic, and that no rotation occurs. What is the maximum compression Al of the bar? Al => m
