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 travel at the same speed as it was when released. Since it is going to travel the same distance up as it is down, the velocity will have an opposite effect meaning that the velocity when it is released will be the same as when it comes back to the spot where it was released from.

· What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion: ->->->->->->->->->->->-> :
The result will be the same because air resistance works both as the ball is being tossed up and as it is falling back down.

10-15 minutes. Probably only a couple minutes to type once I thought the answer through.

The direction of the air resistance changes between upward and downward motions. Revision is optional, but do check the link.
