Given the same ball, what is the change in velocity over the duration of the impact with the ground? Is the answer a vector or scalar?
Added by Mark W.
Step 1
Before the impact, the ball has an initial velocity (which could be zero if it's dropped from rest or a non-zero value if thrown downwards). After the impact, the ball will have a final velocity, which could be zero if it comes to rest or a different value if it Show more…

A ball that is thrown upwards from the ground will eventually reach its highest point and fall back to the ground. Which one of the following vector quantities is always directed in the same direction as the ball travels along this up and down path? The ball's velocity. The ball's acceleration. Both of these. None of these.

How does the magnitude of the vertical component of velocity for a ball tossed at an upward angle change as the ball travels upward? How about the horizontal component of velocity when air resistance is negligible?
