Parabola
-
Let's extend the cannonball program
so that it will plot the trajectory of the cannonball, as we did for the
cos(x) function.
- You must have learned from high school mathematics that the
trajectory of a
projectile will take the shape of a parabola.
Enter the launch angle (in degrees): 30
Enter the initial velocity (in meters/sec): 20
Enter the initial height (in meters): 0
Enter the time interval between position calculations: 0.1
