2. Your initial hypotheses to describe projectile motion are given to you in Eq. 5 and Eq. 6. Write down the mathematical models that you would use to represent Eq. 5 and Eq. 6 (reference p. 2 of the Graphical Analysis guide). Make sure to explain what terms in the physical model the parameters in your mathematical model refer to. 3. Graph these two functions by hand on separate graphs with launching angle on the horizontal axes and time-of-flight and range on the vertical axes, respectively. Use vo = 3.92 m/s. 4. Copy the tables below and fill in the approximate values for time-of-flight and range by reading them off of your hand-drawn graphs. Launching Angle (deg.) 0 15 30 45 60 75 90 Time-of-Flight (s) Launching Angle (deg.) 0 15 30 45 60 75 90 Range (m) Range = x xo t = = 200 g 2002 g sin (Eq. 5) = sin sin 20 g sin cos 0 = (Eq. 6)
