The chipping machine is designed to eject wood chips at ro - 25 ft/s as shown in Fig. 12-22. If the tube is oriented at 30" from the horizontal, determine how high, h, the chips strike the pile if at this instant they land on the pile 20 ft from the tube. 30 20 m SOLUTION Fig. 12-22 Coordinate System. When the motion is analyzed between points O and A, the three unknowns are the height A, time of flight fos, and vertical component of velocity (e),. [Note that (e), (a)] With the origin of coordinates at O. Fig. 12-22, the initial velocity of a chip has components of
