If anotherblock B, having a mass mp, is pressed against A so that thespring deforms a distance d, determine the distance bothblocks slide on the smooth surface before they begin toseparate. What is their velocity at this instant?13-42. Block A has a mass m, and is attached to a springhaving a stiffness k and unstretched length l. If anotherblock B, having a mass mp, is pressed against A so that thespring deforms a distance d, show that for separation tooccur it is necessary that d > 2µ8(ma + mg)/k, where Hiis the coefficient of kinetic friction between the blocks andthe ground. Also, what is the distance the blocks slide on thesurface before they separate?wwwA

14) A block of mass 0.20 kg is against a spring compressed 0.20 m with spring constant 70 N/m. When the spring is released, the block moves along the frictionless surface until entering a region with a coefficient of kinetic friction equal to 0.36 (when the block enters the friction region it is no longer in contact with the spring). How far, L, into the region with friction does the block slide before stopping? k = 70 N/m 0.36 Ax 0.20 m m = 0.20 kg Initial frictionless Ax Final ell frictionless L

A lab assistant has suspended a spring from a door frame. When an object is attached to the spring's bottom end, the spring extends downward by an additional distance, d, measuring 4.80 cm. (That downward distance is relative to the unstretched position that the spring had previously held when in equilibrium, as shown by the horizontal dashed line in the figure below). Calculate the mass of the hanging object (in kg) if the spring constant k has the value 59.5 N/m. 1. kg
Fig. P13.179 and P13.180 B |---| 13.180 A 5-kg sphere is dropped from a height of y = 3 m to test a new spring floor used in gymnastics. The mass of floor section B is 12 kg, and the sphere bounces back upward 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.
