A ball is tossed vertically upward and caught at the position from which it was released.
• Ignoring air resistance will the ball at the instant it reaches its original position be traveling faster, slower, or at the same speed as it was when released?
answer/question/discussion: ->->->->->->->->->->->-> : I believe that the ball’s speed when it reaches the original position would be dependent on how high it went after being tossed, which is dependent on how fast it was moving at its release.
It will be dependent on the initial upward speed, but the question asked for a comparison between initial upward speed and final downward speed.
• What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion: ->->->->->->->->->->->-> : Since air resistance, if it was present, would be present in both directions, it would not change the answer.
