10 problems

10 problems

  • Speed

  • Net force

  • Scale

  • Sliding blocks

  • Max and min forces


Speed

Speed

  • 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 =


Net force

Net Force

  • 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


Scale

Scale

  • 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


Sliding

Sliding

  • 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 = ?


Max min

Max/min

  • 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


You try

You try

  • 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
