Problem 8a
Textbook Question
Textbook QuestionIn the absence of air resistance, a projectile that lands at the elevation from which it was launched achieves maximum range when launched at a 45° angle. Suppose a projectile of mass m is launched with speed into a headwind that exerts a constant, horizontal retarding force Fwᵢₙd = -Fwᵢₙd î. a. Find an expression for the angle at which the range is maximum.
