Question:

If an arrow is shot upward on the moon with a speed of 58 m/s, its height in meters {eq}t {/eq} seconds later is given by {eq}y = 58t - 0.83t^2 {/eq}. (Round your answers to two decimal places.)

(a) Find the average speed over the given time intervals.

(i) {eq}[1, 2] {/eq}

(ii) {eq}[1,1.5] {/eq}

(iii) {eq}[1,1.1] {/eq}

(iv) {eq}[1,1.01] {/eq}

(v) {eq}[1,1.001] {/eq}

(b) Estimate the speed when {eq}t = 1 {/eq}.

Average Rate of Change

In order to find the average rate of change of a function, we're looking for the rate of change of a function between two points. This is the same as finding the slope between these two points, as we're finding the ratio of the change in the function over the change in {eq}x {/eq}.

$$\frac{f(b) - f(a)}{b-a} $$
