Question 1127401: Assume the acceleration of the object is a(t) = −32 feet per second per second. (Neglect air resistance.) A ball is thrown vertically upward from a height of 5 feet with an initial velocity of 72 feet per second. How high will the ball go? Round your answer to two decimal places. Answer by ikleyn(52788) (Show Source):
Under given condition, the height of the ball over the ground level in feet is described by the quadratic function
h(t) = .
Its maximum height will be achieved at t = = = 2 seconds and
will be h(2) = = 85 ft.
The formula t = refers to the general form of a quadratic function
f(x) =
with the negative leading coefficient "a'.
