Homework Help: Math

Posted by A.J. on Saturday, November 21, 2009 at 5:08pm.

Please help if you can.

If a ball is shot projected straight upward at a rate of 64 feet per second from a rooftop, 80 feet above ground level, the height of feet above ground is modeled by the equation,
h(t)=-16t^2+64t+80
Find h(0), h(1),h(2)

Use the zero-factor property to determine how many seconds it will take for the ball to reach the ground? (What value of t makes h(t)=0)
