It appears my copy of the review sheet was different than yours. I have put the solutions below in the order the questions appear on your copy. Email me with any questions.
1. 0 Degrees (180 degrees is minimum resultant, 0 degrees is maxiumum)
2. Arrow up and to the right (use the parallelogram method)
3. 100N (use change in velocity - 10m/s, over change in time - 1.5 s to find acc., then multiply by mass to find the force)
4. 44m (use d = Vit + 1/2at^2, where a = 9.8, t = 3, Vi = 0)
5. decrease (remember because F = Gm1m2/r^2, the distance r plays a greater factor)
6. F (Force of friction only relies on Normal force, and coefficient of friction)
7. Arrow from the box, down and to the left, parallel to the plane (friction always opposes motion)
8. DE (this is where the slope of distance v. time is NOT constant, so velocity must be changing)
9. 10 m/s^2 (use v^2/r, NOT mv^2/r, because we are finding acceleration, not force)
10. copper (its coefficient is the smallest value).
11. 2.0s (Find the average acceleration (Vf + Vi)/2 , then use d = V*t to find t)
12. 1 x 10^ -2 N (mass of insect x velocity of insect)
13. 40m (use Vf^2 = Vi^2 + 2ad)
14. .2h (use distance = average velocity * time)
