If they have the velocities shown, determine their velocities just after direct central impact. Given: M A 2kg = v A1 2 m s = M B 4kg = v B1 5 m s = e 0.4 = Solution: Guesses v A2 1 m s = v B2 1 m s = Given M A v A1 M B v B1 M A v A2 M B v B2 + = ev A1 v B1 + () v B2 v A2 = v A2 v B2 Find v A2 v B2 , () = v A2 v B2

Unformatted text preview: 4.53 1.73 m s = Problem 15-57 The three balls each have weight W and have a coefficient of restitution e . If ball A is released from rest and strikes ball B and then ball B strikes ball C , determine the velocity of each ball after the second collision has occurred. The balls slide without friction. Given: W 0.5 lb = r 3 ft = 337...
