22.4.5. The disc rotates at an angular velocity w = 2 rad / s, hits the vertical wall with the center of mass velocity Vo = 1,8 m / s at an angle a = 45 °. Determine the normal pulse module Sn, if the mass of the disk m = 0.6 kg, and the coefficient of restitution of the normal pulse k = 0.55. (1.18)
