Elastic collision is used to find the final velocities v1' and v2' for the mass of moving objects m1 and m2.
Consider a moving object with the mass of 7kg with initial velocity of 4 ms-1. The mass of the another moving object is 6kg. Find the after collision velocity v1' and v2' of the moving object?
Mass of Moving Object (m1) = 7 kg Mass of Moving Object (m2) = 6 kg Velocity of Stationary Object (v1) = 4 ms-1
v1' = ((m1 - m2) / (m1 + m2)) v1 v1' = ((7 - 6) / (7 + 6)) x 4 v1' = (1 / 13) x 4 v1' = 0.307692308 v2' = (2m1 / (m1 + m2)) v1 v2' = ((2 x 7) / (7 + 6)) x 4 v2' = (14 / 13) x 4 v2' = 4.307692308
