Question 968844: A ball is kicked off the roof of a 35m tall building at a speed of 10m/s. The height of the ball is defined by the function h(t)=-4.9t^2+10t+35, where h is the height of the ball in metres and t is the time in seconds. During which of the following intervals of time is the average rate of change of the ball's height the greatest?
Thanks so much :)
