Finding Final Velocity using Conservation of Momentum &Conservation of Energy Eq

Question

Finding Final Velocity using Conservation of Momentum &Conservation of Energy Equations Find the final velocity of the two balls if the ball withvelocity v2i = -21.3 cm/s has a mass equal to half that of theball with initial velocity v1i =+31.4cm/s Finding Final Velocity using Conservation of Momentum &Conservation of Energy Equations Find the final velocity of the two balls if the ball withvelocity v2i = -21.3 cm/s has a mass equal to half that of theball with initial velocity v1i =+31.4cm/s

Explanation / Answer

Final velocities are            v1f = ( (m1 - m2 ) v1i /(m1 + m2 ) )   - ( 2m2 v2i / (m1 +m2 ) )            v2f = ( (2m1)v1i / (m1 + m2 ) )   - ( (m2 - m1 )v2i / (m1 + m2 ) ) substitute values. substitute values.
