1.
The angle of a circle wouldn't depend on the radius, so that would mean that they both have the same angular displacement.
2. If w = 2(pi) / T then it doesn't depend on the radius either, so the answer would be they're both the same again, right?

Okay, 3 problems I can't seem to get the right answer for..
1. A 2.30-m-long pole is balanced vertically on its tip. It starts to fall and its lower end does not slip. What will be the speed of the upper end of the pole just before it hits the ground? [Hint: Use conservation of energy.]

1. hmm.. I don't really get the 18m/s being in the opposite direction. Does it mean the vi - vf is actually 6+18?
2. I'm pretty sure the problem didn't say how far above the block is but it'll be too late too check. Thanks for your help though :)
I know those problems are on the test tomorrow...
momentum problems - really urgent:)
Two problems I'm stuck on for a test tomorrow morning...
1) A .6 kg tennis ball initially moving at 12m/s is struck by a tennis racket causing it to rebound in the opposite direction at 18m/s. What is the average change in momentum?
I know p=mv but to...
