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:IT will be traveling at the same speed as when it was released.
Gravity acts negitavely on it as it rises, and positively on it as it falls.. Gravity is constant.
What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion:
I am not completely sure. I would think that it would be the same also, since air resistance is present as the ball travels up and down.
air resistance acts in the same direction as gravity while the ball is rising, in the opposite direction when the ball is falling, so there is a difference.
