10 Sliding Two particles with mass m₁ = 2.0 kg and m₂ = 5.0 kg can slide on a frictionless rod. A spring with k = 1000 N/m is attached to m2. The velocity of the first ball is v₁ = 14 m/s and the second is at rest. K M₁ M₁₂ v₁ = 14.0 m/s V₂ = 0.0 m/s a. What is the maximum compression of the spring when the particles collide? b. What are the velocities of the particles after the collision?
