Motion of the CM, 2D:a)Review question: Projectile 1 is fired upward with initial speed 240 m/s, at an angle of 60° above the horizontal. It lands later on the horizontal ground a distance x away. Find x. Show your setup and work. b)An identical projectile 2 is fired with the same initial speed and angle. However at the highest point of its path, it explodes into two pieces, 2A and 2B, each with half the original mass. The explosion forces are horizontal, and have no vertical components. This explosion causes piece 2A to stop at that point, so it subsequently drops straight down. Where does piece 2B land? Explain. c)Sketch the path of projectile 1. On the same figure, sketch the paths of pieces 2A and 2B, from the highest point to the landing point.
