Find the trajectories (height as a function of distance) for initial angles ranging from 15 to 750 . Employ a range of horizontal distances from 0 to 80 m in increments of 5 m. The results should be assembled in an array where the first dimension (rows) corresponds to the distances, and the second dimension (columns) corresponds to the different angles. Use this matrix to generate a single plot of the heights versus the horizontal distances for each of the initial angles. Employ a legend to distinguish among the different cases, and scale the plot so that the minimum height is zero using the axis command.
