If a certain cannon is fired from a height of 8.8 meters above the ground, at a certain angle, the height of the cannonball above the ground, h, in meters, at time, t, in seconds, is found by the function h(t)=−4.9t^2+30.5t+8.8. Find the time it takes for the cannonball to strike the ground.
The cannonball will strike the ground after about ? seconds
(Type an integer or a decimal. Round to the nearest hundredth as needed.)
just solve
−4.9t^2+30.5t+8.8 = 0
in the usual way
