Aball is kicked upward with an initial velocity of 56 feet per second. the ball's height h (in feet) can be expressed as a function of time t (in seconds) by the equation h = -16t2 + 56t. how much time does the ball take to return to the ground?

i can not answer the question due to the fact that you spelled "carton" as "cartoon", a cartoon is something you watch on tv, a carton is a box that holds things. and also you've been waiting for this question for a while so why don't you get off your lazy a** and try to figure it out for yourself for once!
