Question

The area under a graph of vx vs t from t = ti to t = tf represents what?

Answer 1

what is vx ?
velocity times distance?

Answer 2

That I am not sure of, the only options I am given are:

1) xi.
2) xf.
3) xf - xi.
4) (xi + xf).
5) xi + xf.

Answer 3

well I'm not sure either, but\[\int_{ti}^{tf} vdt=x_f-x_i\]but that doesn't have an x in it, that would be for a graph of v vs t

Answer 4

I think someone typed an extra x...

Answer 5

ah, that would do it :P
