Colonel Harry a. Froboess of Switzerland jumped upward and outward from a windonw of a blimp and landed in a body of water on June 22, 1936. His jump was 120m, about the height of a 40-storey building. The path of his jump can be represented by the quadratic relationship h = 120 + 5.5t
- 4.9t^2,where h is the height above the water in metres and t is te time in seconds.
a) Find the maximum height of his dive.
b) How long did it take him to reach the water?
What kind of HELP do you need? You need to be specific when asking questions here.
If all you do is post your entire assignment, with no evidence of thinking on your part, nothing will happen since no one here will do your work for you. But if you are specific about what you don't understand about the assignment or exactly what help you need, someone might be able to assist you.
I just want to know if when I am doing this equation, that the answer to b) is figuring out the x-intercept
