Vectors and Projectile Motion

These questions cover projectiles: resolving the launch velocity, building $\mathbf{r}(t)$ from $\mathbf{a}=-g\mathbf{j}$, flight time, greatest height, range, the Cartesian path and hitting a target. Take $g=10$ m/s${}^2$ unless told otherwise. They start easy and get harder. Stuck? Tap Show a hint for one step at a time.
