An object has been thrown straight up into the air. The formula
h = vt − 16t2
gives the height h of the object above the ground after t seconds, when it is thrown upward with an initial velocity v. An object has been thrown straight up into the air. The formula
h = vt − 16t2
gives the height h of the object above the ground after t seconds, when it is thrown upward with an initial velocity v.

After how many seconds will the object hit the ground if it is thrown with a velocity of 224 feet per second?
t = . sec
