For identical cannons and identical projectiles and identical initial speeds, but different pointing angles, the maximum distance for its projectile is attained for the cannon which launches at
A) 32$\degree$ above horizontal.
B) 45$\degree$ above horizontal.
C) either 32$\degree$ or 58$\degree$ above horizontal.
D) zero degrees-a flat trajectory.

Question

Quizplus · Accepted Answer

The maximum distance for a projectile launched at an angle is achieved when the angle of launch is 45 degrees. This is because at 45 degrees, the projectile has the maximum range and the least amount of air resistance acting against it. Therefore, choice B is the correct answer.
