Two objects travel directly toward each other. Mass 1 = 5.00 kg and has an initial velocity of 5.00 m/s i. Mass 2 = 3.00 kg and has an initial velocity of -1.50 m/s i. a) If the two objects collide inelastically and Mass 2 has a final speed of 3.50 m/s i, what is the final velocity Mass 1? b) What is the change in kinetic energy regarding the collision?3.
