A javelin thrown by an athlete is in ________ motion.

Question

Accepted Answer

1. Identify types:
   - Oscillatory/periodic: repeated back-and-forth motion.
   - Rectilinear: motion along a straight line.
   - Curvilinear: motion along a curved path.
2. A thrown javelin (neglecting air resistance) is a projectile whose trajectory is a parabola under gravity, e.g. $y = x	an	heta - \frac{g x^2}{2 u^2 \cos^2	heta}$, so its path is curved and not repeating.
3. Hence the motion is curvilinear (choice 4), not oscillatory/periodic or rectilinear.
