Question 169121This question is from textbook Elementary and Intermediate Algebra
: Height difference. A red ball and a green ball are simultaneously tossed into the air. Teh 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?
b). How much higher is the red ball 2 seconds after the balls are tossed?
thanks! This question is from textbook Elementary and Intermediate Algebra
You can put this solution on YOUR website! 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
