The table below shows the velocity v(t)of a falling object at various times (time t measured in seconds, velocity v(t)measured in meters per second). $\begin{array}{ccccc}
t & 0 & 1 & 2 & 3 \
v(t) & 19 & 25 & 30 & 34
\end{array}$ Due to air resistance, the object's acceleration is decreasing.What does this tell you about the shape of the graph of v(t)?
A)It is concave down
B)It is concave up
C)Neither of the above

Question

Quizplus · Accepted Answer

The decreasing acceleration indicates that the velocity increases at a decreasing rate, which is characteristic of a concave down graph.
