DUR the as 1 billiards table a cue ball, initially at rest at point on the table, is strucks we stick with a center-of-mass speed v, and a "reverse" spin of angular en force acts on the ball as it initially skids across the table. The mass of the 10 pts) On a level bi 2 (10pts that it leaves A kinetic friction and its and its radius is r. ball is m free body diagram to indicate all forces acting on the billiard ball before it ut slipping and explain why the ball's angular momentum is conserved about (a) (4 points) -)/4 points) Draw a fra starts roll without slipn point o. ing conservation of angular momentum, find the critical angular speedo such Linetic friction will bring the ball to a complete (as opposed to momentary) stop. is 10% larger than o, determine the ball's center of mass velocity ve when 10)( 4points) Using con that, if o, = 0. kinetic (c) (2 points) If o, is 100 DO it starts to roll without slipping Fig. 1
