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
Answer
Explanation:
Step1: Identify 600 feet on the altitude axis.
Locate the horizontal line at 600 feet on the graph.
Step2: Find intersection points with the rocket's altitude curve.
Observe where the horizontal line intersects the curve; these are the time points.
Step3: Read corresponding time values from the x-axis.
Match the intersection points to the time values on the horizontal axis.
Answer:
D. 4.5 and 12 seconds
