Avector a of magnitude 6 and another vector b have a resultant magnitude 12. the vector b:

a. must have a magnitude of at least 6 but no more than 18
b. may have a magnitude of 20
c. cannot have a magnitude greater than 12
d. must be perpendicular to a

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.

Complete the sentence to describe the law of conservation of energy. the law of conservation of energy states that energy cannot be created
