You will now use graphical analysis to calculate the slope of the line. choose analyze from the menu. select automatic curve fit. select the proper stock function from the list. (hint: your answers from question 1 should you make the proper selection.) just below the graph you will see the slope value. remember that the symbol for slope is "m." when you choose ok to get back to the regular graph screen, you will see a little box on the graph. this box also shows the slope value. (remember that slope is "m.") if you are unable to use graphical analysis, you can also graph your data on paper to determine the slope. hint: to determine the slope, use the formula m = (y2 - y1) ÷ (x2 - x1). what is the numerical value of the slope of the line? show your work.

Wo dimensional dynamics often involves solving for two unknown quantities in two separate equations describing the total force. the block in (figure 1) has a mass m=10kg and is being pulled by a force f on a table with coefficient of static friction îľs=0.3. four forces act on it: the applied force f (directed î¸=30â above the horizontal). the force of gravity fg=mg (directly down, where g=9.8m/s2). the normal force n (directly up). the force of static friction fs (directly left, opposing any potential motion). if we want to find the size of the force necessary to just barely overcome static friction (in which case fs=îľsn), we use the condition that the sum of the forces in both directions must be 0. using some basic trigonometry, we can write this condition out for the forces in both the horizontal and vertical directions, respectively, as: fcosî¸â’îľsn=0 fsinî¸+nâ’mg=0 in order to find the magnitude of force f, we have to solve a system of two equations with both f and the normal force n unknown. use the methods we have learned to find an expression for f in terms of m, g, î¸, and îľs (no n).
