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: ->->->->->->->->->->->-> :
The ball will be traveling the same speed when it is caught as when it was released. When the ball is thrown upward gravity is acting against the ball to slow it down until it reaches its peak at vf = 0 m/s. When it comes back down the v0 = 0 m/s and the same component of gravity will cause the ball to accelerate at 9.8 m/s through the same distance.

• What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion: ->->->->->->->->->->->-> :
If air resistance is present the acceleration will be lower because it will slow the ball down as it rises and falls. The faster the ball is moving the greater affect air resistance will have on the ball.
