Grade 12th passGeneral Physics
a. A laser beam is aimed 15.95° above the horizontal at a mirror 11,648 m away. It glances off the mirror and continues for an additional 8570. m at 11.44° above the horizon until it hits its target. What is the resultant displacement of the beam to the target? b. 2) Three forces act on a point: 3 N at 0°, 4 N at 90°, and 5 N at 217°. What is the net force?
