differentiate both sides of this function with respect to x |dw:1436163187408:dw|

in order to find average rate of change during the interval { 1,5} we use this formula

the height ,s , of a ball thrown straight down with initial speed 64ft/ sec froma cliff 80 ft. high is s(t)=-16t^2-64t+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

average rate of change of y respect to x over the interval [1,5] is \[\frac{f(5)-f(1)}{5-1} \text{ where} f(x)=4x+2\] 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

to find velocity just differentiate the position function
myininaya
  • myininaya
but you will have to find when s=0 first
myininaya
  • myininaya
since it wants to know the velocity when it hits the ground (means height is 0 there so that is why we set s=0)
myininaya
  • myininaya
for the last one you will need to consider the left and right limits

what bout 2 and 3?
myininaya
  • myininaya
well have you solved s=0 yet?
myininaya
  • myininaya
and then differentiated s to find v
anonymous
  • anonymous
I got 80
myininaya
  • myininaya
how did you 80 from solving the equation s=0
myininaya
  • myininaya
\[-16t^2-64t+80=0 \\ \text{ you could divide both sides by -16 } \\ t^2+4t+5=0\] can you see if you can solve that?
myininaya
  • myininaya
now this will tell us the value t such that s=0
myininaya
  • myininaya
s=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
anonymous
  • anonymous
oh ok
myininaya
  • myininaya
oops t^2+4t-5=0
Haseeb96
  • Haseeb96
is it -196 ?>
myininaya
  • myininaya
have you solved for t yet?
anonymous
  • anonymous
not one of my choices for number 2
myininaya
  • myininaya
I don't know if you still need help or not...
anonymous
  • anonymous
I don't have an answer for number 2 or 3 lol I have tried everythig
myininaya
  • myininaya
have you actually tried solving the equation I have asked you to yet/
myininaya
  • myininaya
and 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
anonymous
  • anonymous
yes and I am getting big numbers im terrible at it. this is hwat I got- -96 is that right?
