To pass inspection, steel balls designed for use in ball bearings must clear the fixed bar A at the top of their rebound when dropped from rest through the vertical distance H = 40 in. onto the heavy inclined steel plate. If balls which have a coefficient of restitution of less than 0.53 with the rebound plate are to be rejected, determine the position of the bar by specifying h and s. Neglect any friction during impact.

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.
