Randall D. Knight — Kinematics in Two Dimensions: Problem Problem_48

A projectile is launched from ground level at angle \(\theta\) and speed \(v_0\) into a headwind that causes a constant horizontal acceleration of magnitude \(a\) opposite the direction of motion. a. Find an expression in terms of \(a\) and \(g\) for the launch angle that gives maximum range. b. What is the angle for maximum range if \(a\) is 10% of \(g\)?
