Problem 2

A baseball travels \(d\) meters \(t\) seconds after being dropped from the top of a building. The distance traveled by the baseball can be modeled by the equation \(d = 5t^2\).

Complete the table and plot the data on the coordinate plane.

Blank graph, origin O, with grid. Horizontal axis, time, seconds, scale 0 to 3.5, by 0.5’s. Vertical axis, distance traveled, meters, scale 0 to 30, by 5’s.
Is the baseball traveling at a constant speed? Explain how you know.
