y=xtan\theta -(1)/(2)(x^(2)g)/((v_(0)cos\theta )^(2))+y_(0) where y is the height, x is the horizontal distance in meters, \theta is the initial angle, gg=9.81(m)/(s^(2)) v_(0) is the initial velocity in (m)/(s), and y_(0) is the initial height in meters. The range, d, of the projectile is the horizontal distance it travels and can be determined using the formula: d=(v_(0)cos\theta )/(g)(v_(0)sin\theta +\sqrt((v_(0)sin\theta )^(2)+2gy_(0))) Write a script to calculate the following three trajectories: Trajectory1: \theta _(1)=30\deg ,v_(0)=25(m)/(s),y_(0)=3.5(m)/() Trajectory2: \theta _(2)=45\deg ,v_(0)=25(m)/(s),y_(0)=3.5m Trajectory3: \theta _(3)=60\deg ,v_(0)=25(m)/(s),y_(0)=3.5m For each value of \theta , generate a column vector of 200 evenly-spaced x values starting at 0 and ending at the range d. Compute the associated column vectors of y values and assign the results to the variables named y1,y2, and y3 for \theta _(1),\theta _(2), and \theta _(3) respectively. Use the plot command to generate a figure with a plot of all three trajectories on a single set of axes. Use MATLAB commands to add an appropriate title, axis labels, grid and legend to the figure.
