133. (a) Sample Problem 8-3 illustrates simple energy conservation in a similar situation, and derives the frequently encountered relationship: v = 2 gh . In our present problem, the height change is equal to the rod length L . Thus, using the suggested notation for the speed, we have v o = 2 gL . (b) At B the speed is (from Eq. 8-17) 2 0 24 v v gL gL =+ = . The direction of the centripetal acceleration ( v 2 / r = 4 gL/L = 4 g ) is upward (at that
