In this project, you will use parametric equations to model the path of a projectile. Parametric equations use a third variable t to represent time. The variables x and y are written as functions of t. For any time t, the horizontal position xt and vertical position yt of a projectile (ignoring air resistance) launched at ground level are given by the equations xt v0 cos t yt v0 sin t 16t2. In these equations, is the angle with the horizontal and v0 is the initial velocity in feet per second, as indicated in the figure at the left. Set your graphing utility to parametric and degree modes, and use the viewing window shown at the left. Let v0 88 feet per second and 20 and graph the parametric equations xt 88 cos 20t yt 88 sin 20t 16t2. Use the zoom and trace features of your graphing utility to (a) find the maximum height attained by the projectile, (b) find the time at which the maximum height occurs, (c) determine the length of time that the projectile is in the air, and (d) determine the range of the projectile.
Chapter Project Investigations 1. Verify analytically the range of the projectile by solving the equation 88 sin 20t 16t2 0 for t and then evaluating xt at this t-value. 2. Use a graphing utility to find the maximum height and range of the projectile when 30 and v0 132 feet per second. What viewing window did you use? 3. Let v0 60 feet per second and find the maximum range for the angles 20, 30, 40, 50, and 60. In general, what angle should you use to produce the maximum range? 4. What is the relationship between the time the projectile reaches its maximum height and the time it takes for the projectile to return to the ground? Explain. 5. Eliminate t from the parametric equations xt v0 cos t
and
yt v0 sin t 16t 2
by solving for t in the first equation and substituting this value into the equation for y. Show in this case that the height of the projectile is given by the equation y tan x
16 sec2 2 x. v02
Use this equation to find the angle corresponding to a maximum range of 200 feet and initial velocity of v0 80 feet per second.
