Question

22. An expert marksman aims a high-speed rifle directly at the center of a nearby target. A ssuming that the rifle sight has been accurately adjusted for more distant targets, will the bullet hit the near target above or below the center? xplain. Q23. n the diagram, two different trajectories are shown for a ball thrown by a center fielder to home plate in a baseball game Which of the two trajectories (if either), the higher one or the lower one, will resultin a longer time for the ball to reach home plate? Explain

Explanation / Answer

22) since the rifle was accurately adjusted for distance target, if correctly aimed, the bullet will be released at a slight upward angle to counteract the effects of gravity in long distance flight. Since the target is nearby, the bullet will not be under the force of gravity long enough to be pull it below the target. So it should land above the center of the target.

23)  The higher trajectory will result in a longer time because its initial vertical velocity component is larger.
