Homework Statement
My problem is that I am given a bunch of labelled curves on a velocity-time graph that I have to match up with 2 given situations. The first situation is an egg being dropped from a bridge with no initial velocity. The second situation is an egg being thrown downward off of the bridge.
The Attempt at a Solution
Now, I was able to match up the first situation with the only curve that had a decreasing, linear slope beginning with an initial velocity of 0. For the second situation, it is clear to me that the curve should have a steeper, still negative slope. My problem is that I am not sure whether, in the second situation, the initial velocity is positive or negative. Can someone explain which it is and why it is that?
