+h=-16%5E2%2Bvt%2Bs+
word problem: A cat leaps into the air with an initial velocity of 8 feet per second to grab a string, and then falls back to the floor. How long does the cat remain in the air?
---------------------
+h%28t%29+=+-16%5E2%2Bvt%2Bs+
it's +h%28t%29+=+-16t%5E2%2B8t+ not 16^2
v = 8 ft/sec, s = 0
----------
+h%28t%29+=+-16%5E2%2B8t+
Solve for h(t) = 0
One t is the time the cat jumps, the other is the time it returns to ground level.
------------
+h%28t%29+=+-16%5E2%2B8t+
-16%5E2%2B8t+=+0
t = 0, t = 2
The cat is off the ground for 2 seconds.
