Question

915mm 4. Two snooker balls are at rest when they are struck simul- taneously, rolling along the paths AC and BC with the ve- locities shown. (1) Determine the angle that is required to cause the two balls to collide. Hint: consider what the relative motion vector needs to be. (ii) If the initial dis- tance between them is 1 200 mm, and ball A struck at angle 0 = 60° as shown, with a velocity of 400 mm/s (while vs remains the same as before), what is the minimum distance between the balls, if they roll with constant velocity? (Ans. B 610 m/s

Answer 1

152 smis A 792 yinmis NOW aif the resultant of these two velouties in in the direction ( AB) then only these two balls wil so 792.41 tone = ao - 79 lo Aw 152.5
