If you're still stuck, but remember, there are plenty of people on campus who know how to do these....and you'll be better off if you figure them out on your own.
1. A>b>c>e>d, but d is fastest, c is slowest...
2. Which makes more sense, b or c
3. V=delta x/t
4. Sqrt(150^2+150^2)
5. Faster, constant
6. Rectangle plus triangle
7. A= delta v / t
8. Granddaddy
9. See #7
10. =+-
11. D=slope*V + 0
12. Extrapolate
13. Slope
14. A=F/m
15. Fn=W...
16. A=F/m. If 4m, then a is now...
17. Terminal v
18. 1 left...
19. Fn+Fpx=Fg, so...
20. No a, so W=mg
21. W= F(9.8+2)
22. Pythagoras
23. Equilateral triangle
24. Granddaddy to find t, then t*30
25. Normally a is 9.8 down v=0, but since its moving sideways, v is > 0
