Question 1140224: If you throw a ball straight up from a rooftop 160 feet high with an initial speed of 48 feet per​ second, then the formula h=-16t^2+48t+160 describes the​ ball's height h feet above the​ ground, t seconds after you released it. The ball misses the rooftop and eventually strikes the ground.
A) What is the height of the ball one second after you release​ it?
Solution​:Find
the value of h in the formula h=−16t^2+48t+160 when t​ = 1.
h​ =_____feet
the answer i got was 192
​b) How long will it take the ball th hit the​ ground?
Solution​:Find the value of t in the formula h=−16t^2+48t+160
when h​ = 0.
It will take _____ seconds for the ball th hit the ground.
the answer i got was 5
