Physics: Friday, March 9th

Here are the answers to your fake quiz. Sorry #6 is unreasonable. I stole it that way.
1)10.71 kg m^2 
2)1.4 x 10^6 kg m^2
3)1.9 m/s^2
4) (a)5.55 N (will be 3 sfs on the quiz)
    (b)10.45 N (will be 3 sfs on the quiz)
5)25 m/s
6) (a) v = 14 m/s 
    (b) 4.5
I'm going to slightly change the numbers for each, and 6 will be more reasonable
