A projectile is fired vertically from point A with an initial speed of 290 ft/sec. Relative to an observer located at B, at what times (find two times t < t2) will the line of sight to the projectile make an angle of 27° with the horizontal? Compute the magnitude of the speed of the projectile at each time, and ignore the effect of aerodynamic drag on the projectile. 290 ft/sec В 270 505'
