Question 209449: If a penny is thrown downward at 30 ft/sec
from the bridge at Royal Gorge, Colorado, how long does it
take to reach the Arkansas River 1000 ft below?
It says to use the quadratic equation.
x^2-〖30〗^2=〖1000〗^2
I have work started but it's not pasting into here.
It's from my online textbook, I cannot find the ISBN.
You can put this solution on YOUR website! If a penny is thrown downward at 30 ft/sec
from the bridge at Royal Gorge, Colorado, how long does it
take to reach the Arkansas River 1000 ft below?
It says to use the quadratic equation.
-----------
The height of an object (neglecting air friction) is
h(t) = -16t^2 + vt + h0 Where v is the starting speed and h0 is the initial height. t is in seconds, h in feet.
In this case h0 = 1000 ft, and v = -30 ft/sec (-30 since it's thrown downward)
Find when h(t) = 0
0 = -16t^2 - 30t + 1000
-8t^2 - 15t + 500 = 0
