Statement of a problem № 10217


A 5 kg sphere is dropped from a height y=3 m to test a new spring floor used in gymnastics. The mass of the floor section B is 12 kg, and the sphere bounces back upwards a distance of 44 mm. Knowing that the maximum deflection of the floor section is 33 mm from its equilibrium position, determine (a) the coefficient of restitution between the sphere and the floor, (b) the effective spring constant k of the floor section.
