If a postion vs. time plot is rising in time (but not in such a way as to produce a vertical line on the graph) then we can know for certain that ______________________________...
a) velocity is changing
b) velocity is constant
c)position is constant
d) acceleration is constant
e) acceleration is changing
f) it has a velocity <0 and velocity is changing
g) it has a velocity > 0 but we don't know if the velocity is constant
h) we can't know any of these

G is the right answer

Yes, it would be g for the information given.
If the plot is a rising straight line, the velocity is constant. If the plot is a rising curve, the velocity is changing.
If the plot is rising in a straight line, you also know the acceleration is constant (it would be 0).

Yes, of course it's G. Unless you have some other information.
