A ball is thrown straight up into the air with an initial velocity, travels up, then comes back down into the person's hand. How does the velocity-time graph change: if the ball lands lower than the position it started from? if the ball lands above its starting point?

If the ball lands at it's starting point, the magnutude of the final velocity would be the same as the initial velocity.
If the ball lands lower the graph would be longer and the mag. of the final vel. would be greater than the initial.
If the ball lands higher, the graph will be shorter and the mag. of the final vel. would be less than initial.

The fact that you want to find the velocity at a lower or higher point of flight should not change the trejectory of the ball, because the physics laws that apply are the same. You may have to extend the graph to find the velocity at a particular time/distance.
