You can type in values for speed, angle and drag. The trajectory will be drawn for you along with the horizontal and vertical components of velocity. The Range, Maximum height and the flight time are also calculated and displayed. You may want to use small values for drag. If you don't see the curve, try with smaller values for drag.

A non zero value for drag will give a trajectory of a projectile of Model 2. Compare the values of range, flight time and maximum height to those of an ideal projectile.
