A hobby rocket reaches a height of 72.3 m and lands 111 m from the launch point with no air resistance. What was the angle of launch?
A) 69.0°
B) 67.4°
C) 22.6°
D) 44.8°

Question

Quizplus · Accepted Answer

The correct answer is A because the angle of launch can be calculated using the formula:θ = arctan(2 * h / d)where h is the height reached by the rocket and d is the horizontal distance traveled by the rocket. Plugging in the given values, we get:θ = arctan(2 * 72.3 m / 111 m) = 69.0°
