Question

The height, h, of a falling object t seconds after it is dropped from a platform 300 feet above the ground is modeled by the function h(t)=300-16t2

Which expression could be used to determine the average rate at which the object falls during the first 3 seconds of its fall?

Answer 1

h(3) - h(0)

Explanation:

I graphed the function on the graph below and graphed the point (3,156) to find the height of the object after 3 seconds. The average rate of falling is -144
