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 based on the impulse momentum theorem

• What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion: ->->->->->->->->->->->-> :
There would be nothing different, because air resistance acts upon the ball in both directions the same amount.

@& Air resistance acts in the direction of gravity when the ball rises, opposed to the direction of gravity when it falls.
