Recall that the height of an object t seconds after it begins moving when gravity is the only force acting on the object is given by
h(t)=−16t2+v0t+h0,
where h(t) is given in feet, v0 is the initial velocity of the object in ft/sec, and h0
is the initial height of the object in feet.
if a ball is thrown directly upward from the top of a building with an initial velocity of 60
feet per second, and an initial height of 75 feet. what is the maximum height attained by the ball?
your answer is feet.
