Well both A and C are wrong.

C is wrong because there is no negative velocity.

A is wrong because velocity is a function of displacement from the ground and yet the graph is clearly, not a function.

The proper way to draw it would be sine wave.

How the fuck does a guy who switches from Architecture to Physics, because it was easier, become a professor?

Americans should not be allowed anywhere near science. I wish there were flags on this board so they would be laughed out of here

Fuck off faggot

Velocity isn't a function of displacement. Given a displacement, there are two corresponding velocities (downwards and upwards). A is correct

Okay I just watched the questions, but I haven't looked at the answers yet. Here is what I got:

1: A
It is velocity vs height.

2. A C D
Really did have a clear idea on this one, here is my best guess.

3. A, C
You have to calculate terminal voltage, and use Kirchhoff's second rule to find the voltage between a and b.

4. B
I know no other answer is right, so B seems like the right choice.

5. A C
Total guess, have no idea


>ok, just watched the answers

I got 3/5, that proves I am as smart as a professor, end of story.

Says who?

>The proper way to draw it would be sine wave.
I think he trolling. X represents height. A sine wave means that it bounces off the ground and goes into the sky forever.
