4. Two particles of mass m₁ = 0.260 kg and m₂ = 0.150 kg collide on a smooth horizontal surface as shown in the diagram. They bounce off each other as shown. Take v₁ = 0.540 m/s, v₂i = 0.900 m/s, and v₁f = 0.700 m/s. Assume the collision occurs for 0.030 s. (i) Do a numerical calculation to prove whether this collision is elastic or inelastic. (ii) What is the average force on m₁ during the collision? (iii) What is the average force on m2 during the collision? (iv) How does your answer in (ii) and (iii) compare?
