common velocity

15–35. The 5-Mg bus B is traveling to the right at 20 m> s. Meanwhile a 2-Mg car A is traveling at 15 m> s to the right. If the vehicles crash and become entangled, determine their common velocity just after the collision. Assume that the vehicles are free to roll during collision.

 

 

 

vB = 20 m/s

B                       v   = 15 m/s

15–38.   A railroad car having a mass of 15 Mg is coasting at

1.5 m>s on a horizontal track. At the same time another car having a mass of 12 Mg is coasting at 0.75 m>s in the opposite direction. If the cars meet and couple together, determine the speed of both cars just after the coupling. Find the difference between the total kinetic energy before and after coupling has occurred, and explain qualitatively what happened to this energy.
