The Table Below Shows the Velocity V(t)of a Falling Object $\begin{array}{ccccc}t & 0 & 1 & 2 & 3 \\v(t) & 19 & 25 & 30 & 34\end{array}$

question 68

Multiple Choice

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
