- Force The force F (in pounds) on a person’s back when he or she bends over at an angle from an upright position is modeled by F=0.6Wsin+90sin12 where W represents the person’s weight (in pounds). (a) Simplify the model. (b) Use a graphing utility to graph the model, where W=185and090. (c) At what angle is the force maximized? At what angle is the force minimized?arrow_forwardCONCEPTS For an object in simple harmonic motion with amplitude a and period 2/, find an equation that models the displacement y at any time t if a y=0 at time t=0: y= ____________. b y=a at time t=0: y= ____________.arrow_forwardTrajectories Are Parabolas From the graphs in Figure 3 the paths of projectiles appear to be parabolas that open downward. Eliminate the parameter r from the general parametric equations to verify that these are indeed parabolas. Figure (3) Paths of projectilesarrow_forward
