Firing a Missile The initial speed of a missile is 330m/s. a At what angle should the missile be fired so that it hits a target 10 km away? You should find that there are two possible angles. Graph the missile paths for both angles. b For which angle is the target hit sooner?
Some stores use an indirect method of observation. The purpose may be for safety to avoid collisions or to foil the attempts of would-be shoplifters. In this situation, a mirror see EF in the drawing is placed at the intersection of two aisles as shown. An observer at point P can then see any movement along the indicated aisle. In the sketch, what is the measure of GEF?
