## Projectile Problems

__Level of difficulty__: variable, algebra to precalculus

This set includes a variety of problems dealing with 2-dimensional motion in a uniform
gravitational field. A projectile must be fired so as to hit a motionless or accelerating
target. The projectile's launch velocity and elevation may be chosen by the user. The
target's initial position and velocity and its acceleration may also be chosen. The
gravitational field strength may be varied. In the example below, the horizontal component of
the projectile's velocity is set equal to the target's speed.
