Question

From the user's perspective, the beam serving them μst be within ___ degrees of vertical.

a) 30
b) 45
c) 60
d) 90

Answer 1

The question is about projectile launch angles. A 90° launch angle yields zero range, same as a 0° angle. For maximum range, the optimal launch angle is 45°.

Step-by-step explanation:

The question seems to refer to optimum projectile launch angles, a concept from physics related to motion and trajectory. When a projectile is launched straight up, its range on level ground would be zero, which corresponds to a 90° launch angle. Conversely, if it's not launched at all (0°), the range is also zero. The optimal angle for maximum range is 45°, as it provides the perfect compromise between vertical and horizontal components of the throw.
