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 left parenthesis t right parenthesis equals negative 4.9 t squared plus 30.5 t plus 8.8. find the time it takes for the cannonball to strike the ground.

It would take approximately 6.50 second for the cannonball to strike the ground.

Step-by-step explanation:

Consider the provided function.

We need to find the time takes for the cannonball to strike the ground.

Substitute h(t) = 0 in above function.

Multiply both sides by 10.

For a quadratic equation of the form the solutions are:

Substitute a = -49, b = 305 and c=88

Ignore the negative value of t as time can't be a negative number.

Thus,

Hence, it would take approximately 6.50 second for the cannonball to strike the ground.
