Question

a body of mass 8 k.g. moving with a velocity of 14 m/s along straight line collides with another body of mass 5 k.g. moving the same direction with a velocity of 5 m/s. after collision, the velocity of the heavier body becomes 7m/s. calculate the final velocity of the other body.

Answer 1

first mass =m1=8kg second mass = m2=5kg first velocity =v1=14m/s second velocity =v2=5m/s after collision velocity heavier becomes 7m/s .final velocity =
