In a car lift used in a service station, compressed air exerts a force on a small piston of circular cross-section having a radius of 3.92 cm. this pressure is transmitted by a liquid to a second piston of radius 15.6 cm. what force must the compressed air exert in order to lift a car weighing 14600 n? answer in units of n.

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.
