A ball is tossed into the air with an upward velocity of \(16\) feet per second from the top of a building \(32\) feet high. The equation that gives the height of the ball above the ground at any time \(t\) is \[h=32+16t-16t^2\] Factor the right side of this equation and then find \(h\) when \(t\) is \(2\).
