Question

If an object is dropped from a tall building, then the distance it has fallen after t seconds is given by the function d(t) = 16t2 (in seconds). Find its average speed (average rate of change) over the interval 1 second and 5 seconds.

Answer 1

Step-by-step explanation:

The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 12 = 4.9 meters. After two seconds it will have fallen 1/2 × 9.8 × 22 = 19.6 meters; and so on.
