## Fundamentals of Physics Extended (10th Edition)

The angle of launch that creates the greatest displacement is 45$^{\circ}$. If Curve 1 is less than 45$^{\circ}$, then by default Curve 2 has to travel a shorter distance. If Curve 1 is greater than 45$^{\circ}$, then the angle of Curve 2 must be known to determine the answer.
