8. A projectile is fired from the origin in a straight line towards a rectangular target and hits it perpendicularly 2 seconds later. The vertices of the rectangle are (50,100,275), (100, 0, 275), (200,50, 150), and (150, 150, 150), where units are in meters. (a) At what point did the projectile hit the rectangle? (b) The projectile was trying to hit the center of the target. How accurate was it? (c) Assuming the projectile was moving at a constant speed,...
