Question 169121
A red ball and a green ball are simultaneously tossed into the air. 
The red ball is given an initial velocity of 96 feet per second, and its height t seconds after it is tossed is -16t^2 + 96t feet. 
The green ball is given an initial velocity of 80 feet per second, and its height t seconds afer it is tossed is -16t^2 + 80t feet.
------------------------------------------------------------------- 
a.)Can you find polynomial D(t) that represents the difference in the height of the two balls? 
D(t) = (-16t^2 + 96t) - (-16t^2 + 80t) = 16t
-------------------
b). How much higher is the red ball 2 seconds after the balls are tossed? 
D(2) = 16*2 = 32 feet
