Radar tracks the flight of a projectile. At time the radar measures the horizontal component vx(t) and the vertical component vy(t) of the projectile's velocity and its range R(t) and elevation ((t). Are these measurements sufficient to compute the horizontal distance D from the radar to the launch point of the projectile? If so, derive the expression for D as a function of g and the measured values vx(t), vy(t), R(t), and φ(t).
