Best ResponseYou've already chosen the best response.4in order to find average rate of change during the interval { 1,5} we use this formula

Best ResponseYou've already chosen the best response.0the height ,s , of a ball thrown straight down with initial speed 64ft/ sec froma cliff 80 ft. high is s(t)=16t^264t+80, where t is the time elapsed that the ball is in the air. what is the instantaneous velocity of the ball when it hits the ground? 256 96 0 112

Best ResponseYou've already chosen the best response.3average rate of change of y respect to x over the interval [1,5] is \[\frac{f(5)f(1)}{51} \text{ where} f(x)=4x+2\] or since f(x)=4x+2 is just a line you could use the slope of this line to determine the average rate of change over any given interval

Best ResponseYou've already chosen the best response.3but you will have to find when s=0 first

Best ResponseYou've already chosen the best response.3since it wants to know the velocity when it hits the ground (means height is 0 there so that is why we set s=0)

Best ResponseYou've already chosen the best response.3\[16t^264t+80=0 \\ \text{ you could divide both sides by 16 } \\ t^2+4t+5=0\] can you see if you can solve that?

Best ResponseYou've already chosen the best response.3now this will tell us the value t such that s=0

Best ResponseYou've already chosen the best response.3s=0 means the height=0 we want to find t such that when this happens so we can find the velocity when the ball hits the ground

Best ResponseYou've already chosen the best response.3and then differentiating the position function to find the velocity function and then entering the number you found from solving s=0 into velocity function to find the velocity when the ball hits the ground
