document.write( "Question 88522: I have a formula and a problem. please help step by step Thanks
\n" );
document.write( "An object that is falling or vertically projected into the air has its height, in feet, above the ground given by s=-16t2+vot=so formula
\n" );
document.write( "where s is the height in feet, vo is the original velocity of the object in feet per second, t is the time the object is in motion, in seconds, and so is the height, in feet, from which the object is dropped or projected. A ball is thrown straight up from a rooftop at an original velocity of 80 feet per second from a height of 96 feet. The ball misses the rooftop on its way down and eventually stikes the ground. How high will the ball be 4 seconds after being thrown. The book states 160 feet but how do I put this in formula. Thanks
