Two objects, both with a mass of 1.72 kg are sliding across a horizontal, frictionless surface toward each other. If mass 1 has an initial velocity of 4.17 m/s i  and mass 2 has an initial velocity of -2.08 m/s i, what is the change in total kinetic energy if they undergo a perfectly inelastic collision? Assume that total momentum is conserved.

Two masses undergo a front-to-back colli- sion. The masses are mi m, with initial velocity 2v0, and m₂ = 4m, with initial ve- locity vo. Due to the collision, they stick together, forming a compound system. 20 Vo G m₁ If m= 2.2 kg and vo= 3.9 m/s, find the magnitude of the loss in kinetic energy after the collision.
