Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth.
A rocket is launched from atop a 55-foot cliff with an initial velocity of 138 ft/s.
a. Substitute the values into the vertical motion formula mc012-1.jpg. Let h = 0.
b. Use the quadratic formula find out how long the rocket will take to hit the ground after it is launched. Round to the nearest tenth of a second.
(Hello! I can only solve its time to hit the ground.)
Answer:
The time rocket took to hit the ground after it is launched is approximately at 8.16 seconds.
Step-by-step explanation:
Given:
Formula:
Using this constant-acceleration equation and the quadratic formula , by getting the highest positive answer only, we can find the time it took.
Equation:
Solution:
where:
a = = 4.905
b = = - 42.0624
c = = 16.764
