Question

A 4.90-kg ball, moving to the right at a velocity of +2.50 m/s on a frictionless table, collides head-on with a stationary 8.00-kg ball. Find the final velocities of the balls if the collision meet the following conditions.
(a) elastic
4.9-kg ball =
8-kg ball =

(b) completely inelastic
Both =

Answer 1

(a) v₁= (m₁-m₂)v₁₀/(m₁+m₂),
v₂={2m₁v₁₀}/(m₁+m₂).
(b)
u=m₁V₁₀/(m₁+m₂)
