Question 1205911
A tennis ball is thrown on an incline off a 8m high ledge. if the height of the ball can be represented by the equation {{{ h= t^2+2t+8 }}}, where h is equal to the height of the ball in meters, and t is equal to the time in seconds for it to reach the ground, find out how long the ball will take to hit the ground, and the maximum height it can reach before it hits the ground.

"thrown on an incline"  ???
==============
{{ h= t^2+2t+8 }}}
h will never equal zero for positive values of t
