In a game of pool, ball A is moving with the velocity v0 = v0i when it strikes balls B and C, which are at rest side by side. Assuming frictionless surfaces and perfectly elastic impact (i. e., conservation of energy), determine the final velocity of each ball, assuming that the path of A is (a) perfectly centered and that A strikes B and C simultaneously, (b) not perfectly centered and that A strikes B slightly before it strikes C.

What is magnetic flux? explain faraday's law of induction.

What is the earliest point in the universe that we can observe? why can’t we see back further than this?

Mutt and jeff are running along a path each pushing a cart loaded with rocks. if mutt's wagon has a mass two times greater than jeff's and they want to stay together, arriving at their destination at the same time, what must happen? a) jeff should slow down so mutt can catch up. b) mutt must use half as much force to push his cart. c) mutt must use twice as much force to push his cart. d) mutt and jeff will use the same force, but mutt will take bigger steps.
