This model illustrates the motion of a projectile. You can change the projectile?s initial altitude, as well as the absolute value and the direction of its velocity. Note that in the "Stroboscope" mode, the projectile?s velocity vector and its projections onto the horizontal and vertical axes are displayed in equal time intervals. Determine the correlation between the projectile?s initial angle and the maximal horizontal distance it can travel at any given initial angle and the initial altitude y = 0.
