- S = d/t
- d = 45 m, t = 9 s, s =
- S = 77 m/s, t = 10 s, d =
- D = 450 km, s = 18 hr, t =
- D = 900 m, s = 50 m/hr, t=
- T = 50 min, s = 60 mi/hr, d =
- T = 9 hr, s = 40 m/hr, d =

- Of you sitting/standing?
- 8902 N to left, 74902 N to left
- 7980 N to left, 7980 N to right
- 7025 N to left, 7920 N to right
- One force twice the other, both to left
- One force twice the other, larger to left
- Equal forces to left
- Equal forces to left and right

- How many scales to stand on if you want
- 1/2 your weight
- 1/8 your weight

- What the scales would read if
- 300 N person stands on two scales, one is twice the other
- 300 N person stands on three scales, one is twice another, but the other two are equal

- We slide a box across the floor to the left 70 N. What is the force of friction? What direction?
- I push a box 60 N to left. My brother pushes it 160 N to right. Net force on box = ? Friction =?
- I push a box with an equal force as you in the same direction. What is the force of friction?
- I push a desk in a different direction as you with the same force. Net force = ? Friction = ?

- Between
- 789 N and 8790 N
- 790 N and 7671 N
- 6146 N and 6718 N
- 57189 N and 678 N
- 3059 N and 7891 N
- 5194 N and 786N
- 86 N and 781 N

- P. 13 and 31 – all problems but the key terms
- This will be graded.
- You can skip to the problems or things you’d like to practice more
