Question

The position-versus-time plot of a boat positioning itself next to a dock is shown in the figure
Rank the six points indicated in the plot in order of increasing value of the velocity v, starting with the most negative

Answer 1

you are being asked to visualize the slopes of the lines tangent to the curve at the various points given

Answer 2

for example, the slope at C is negative, because the curve is going down
the slope at E is positive
a couple places the slope is 0

Answer 3

C (ABDF) E

C is negative velocity
ABDF ae all constant

so the answer is: C,A,B,D,F,E
