Question

the graph below shows the altitude, in feet, of a model rocket t seconds after launch. during this time, the rocket experiences three distinct modes of flight. initially, the engine accelerates the rocket upward. the rocket then coasts upward, is slowed by gravity, and eventually begins to fall. last, a parachute opens and the rocket drifts smoothly back to the ground. when was the model rocket 600 feet above the ground? 4.5 seconds 7 seconds 7 and 9.5 seconds 4.5 and 12 seconds

Explanation:

Step1: Analyze the graph

We need to find the values of \(t\) (time) when \(y = 600\) (altitude).

Step2: Locate the points

Looking at the graph, we can see that the rocket is at 600 feet at two different times. One is when it is going up (around 4.5 seconds) and the other is when it is coming down (around 12 seconds).

Answer:

4.5 and 12 seconds
