Question 193236: I'm having a little trouble with this problem: Brent throws an object downward with initial velocity of -10 feet per second. The object travels a distance ,where h = height in feet, v = initial velocity, s = initial height in feet, and t = time in seconds. If Brent is standing on a cliff 31.5 feet above the ground, in how many seconds will the object reach the ground?

in general
for this situation
Set s = 0
t = 9/8 seconds = 1.125 seconds
