An Object of Mass M Is Moving with Velocity V

question 36

Multiple Choice

An object of mass M is moving with velocity V . Three smaller objects each of mass m are initially at rest. After the collision the small masses have velocities given by v( + ) , v(2 - ) , and v(2 - 2 ) . If m = M/6 and v = V/3, then the final vector velocity of the mass M is

• A) 15V /18 + V /9
• B) 23V /18 + V /9
• C) 13V /6 + V /3
• D) 13V /18 + V /9
• E) 23V /18 + V /3
