Question

The height of a ball dropped from a tall building is modeled by the equation d(t) = 16t^2 where d equals the distance traveled at time t seconds and t equals the time in seconds. What does the average rate of change of d(t) from t = 2 to t = 5 represent?

Answer 1

A. The ball falls down with an average speed of 336 feet per second from 2 seconds to 5 seconds.

B. The ball falls down with an average speed of 48 feet per second from 2 seconds to 5 seconds.

C. The ball travels an average distance of 336 feet from 2 seconds to 5 seconds.

D. The ball travels an average distance of 48 feet from 2 seconds
