Problem: Consider the head-on collision of two masses, m1 = 3 kg moving to the right with speed 6 m/s and m2 = 6 kg moving to the left with speed 3 m/s. Given that they stick together after the collision, what is the increase in internal energy of the system during the collision? Assume no energy is lost to the surroundings and neglect any external forces acting on the two masses. 1. 81.0 J 2. 56.25 J 3. 40.5 J 4. 216.0 J 5. 303.75 J 6. 112.5 J 7. 144.0 J 8. 375.0 J 9. 525.0 J 10. 72.0 J
