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.
