SOLUTION: NASA launches a rocket at t=0 seconds. It’s height, in meters above sea-level, as a function of time is given by h(t)= -4.9t^2+220t+311. Assuming that the rocket will splash down

Question 1174006: NASA launches a rocket at t=0 seconds. It’s height, in meters above sea-level, as a function of time is given by h(t)= -4.9t^2+220t+311. Assuming that the rocket will splash down into the ocean, at what time does splashdown occur?
The rocket splashes down after how many seconds?
How high above sea-level does the rocket get at its peak?

your second and third questions express the same thought.

Do not repeat it TWICE - - - we, the tutors, are smart enough to understand after first reading,
