Caboose Car
To 29000 kg of freight car collided with a caboose car stopped. The two together, and 22 percent or?
To 29000 kg wagon car collided with a freight caboose stopped. The two together, and 22 percent of the initial kinetic energy is dissipated as heat, sound, vibration, etc. What is the mass of the caboose? Any help? I know I need m1v1 = (M1 + M2) VF, but I have two unknowns and do not know how to find them.
Kf = 0.88Ki ½ (2m) (VF) ² = ½ (0.88) (m) (vi) ² (VF) ² = 0.44 (vi) ² vf = sqrt (0.44) vi
