Solve the equation. Round to the nearest tenth, if necessary.If an object is thrown upward from the ground with an initial velocity of 48 ft/sec, its height after t seconds is given by h = 48t - 16t2. Find the maximum height attained by the object. (The object will attain maximum height exactly at the halfway point in terms of the time t, where t = 0 is at the beginning of the object's flight, and the final time is when the object hits the ground.)
A. 20 ft
B. 32 ft
C. 36 ft
D. 48 ft
