A kicker punts a football from 3 feet above the ground with an initial velocity of 47 feet per second.1) write an equation that gives the height (in feet) of the football as a function of the time (in seconds) since it was punted. 2) Find the height (in feet) of the football 2 seconds after the punt. And,3) calculate how many seconds after the punt the ball would hit the ground.

It matters in what direction the initial velocity is directed.IE, what angle?
the nice wikipedia article on trajectory gives the equation, including the angle involved.
