A helicopter is moving horizontally at a constant speed when it drops a package from a certain height. What will be the observed path of the package when viewed from the ground ?
A straight vertical line
A straight horizontal line
A parabola
A circle

Solution:

\[ y = -\frac{g}{2 v_x^2} x^2 \]

This is of the form y=ax2y = ax^2, which represents a parabolic path. Hence, the object follows a parabolic trajectory when viewed from the ground.
