1. Newton’s Second Law

4. We can also find Ffriction, the coefficient of friction, or the Fnormal using:
Ffriction = μ * Fnormal

8. What is the coefficient of friction?

9. Ffriction = μ * Fnormal
5N = μ * 100 N
0.05 = μ

10. What is the coefficient of friction?

11. Ffriction = μ * Fnormal
5N = μ * 50N
μ = 0.1

17. A = 50N (horizontal must be balanced)
B= 200 N (vertical must be balanced)
C= 1100 N (to have Fnet of 200N, up)
D= 20 N (to have Fnet 60N, left)
E= 300 N ( vertical must be balanced)
F= H= any number you wish as long as F equals H)
G = 50 N ( in order to have a Fnet of 30N, right)
