Answer 1

Answer:

1. 206 feet

2. 7.088 seconds

Step-by-step explanation:

1. Since gravity happens, if you were to graph this equation it would form a parabola. The vertex would then be the highest point. So, after 3.5 seconds, the rocket starts falling again. So the highest point is at 3.5 seconds, which would be 206 feet.

2. Again if you look at the graph, it will be at 0 height at the end of the parabola on the right side. It hits the ground at 7.088 seconds. You can also use an equation. Make the equation equal to 0 then solve for t. You will get two times, -0.088 and 7.088. The negative doesn't work in this case because you can't have negative time. So, the answer is 7.088.
