A flight attendant on an airplane travels 6085 kilometers east from Washington D. C. to Madrid in a time of 9.5 hours. they then travel 9,990 kilometers east to Seoul in 13.5 hours. what was the average speed of the flight attendant? what is the average velocity of the flight attendant

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
