Answer:
And since the time can't be negative we have that:
So the answer for this case would be after 10.36 seconds the rocket will hit the ground
Step-by-step explanation:
For this case we have the function of the height in terms of the time givenby:
And we want to known when the rockect hit the ground and for this case we need to solve the equation
And as we can see we have a quadratic equation like this one:
Where:
And the general solutions are given by:
If we replace the values that we have we got:
And since the time can't be negative we have that:
So the answer for this case would be after 10.36 seconds the rocket will hit the ground
