(a)
Find the maximum height of the rocket will reach.
(a)
Answer to Problem 55HP
The rocket will reach the maximum height of 160 m.
Explanation of Solution
Given:
Bill Launches a model rocket from ground level. The rocket`s height h in meters is given by the equation
What is the maximum height of the rocket will reach?
Concept Used:
Substitute 0 for h and find the vertex of the equation
The vertex of a quadratic equation is:
Calculation:
Substitute 0 for h and find the vertex of the equation
The vertex of a quadratic equation is:
Therefore, the rocket will reach the maximum height of 160 m.
Thus, the rocket will reach the maximum height of 160 m.
(b)
Find the time needed after it is launched the rocket will reach its maximum height.
(b)
Answer to Problem 55HP
It will rake 5.7 seconds to reach the maximum height.
Explanation of Solution
Given:
Bill Launches a model rocket from ground level. The rocket`s height h in meters is given by the equation
How long after it is launched will the rocket reach its maximum height? Round to the nearest tenth of a second
Concept Used:
The vertex of the equation is (5.7, 160). Therefore, it will rake 5.7 seconds to reach the maximum height.
Thus, it will rake 5.7 seconds to reach the maximum height.
(c)
Find the time needed after it is launched the rocketwill land.
(c)
Answer to Problem 55HP
The rocket will land in
Explanation of Solution
Given:
Bill Launches a model rocket from ground level. The rocket`s height h in meters is given by the equation
How long after it is launched will the rocket land? Round to the nearest tenth of a second
Concept Used:
The rocket will land in
Thus, the rocket will land in
