Homework Statement


Im working on a project for school. We're suppost to learn something and teach it to the class, and im having a hard time with this one. What im looking for is an equation. I just don't know how to work height into what I have figured out so far. It is projection based.

Looking for range.
V(in)= 80 m/s
Angle= 45
Starting height Height= 7.5 ft


Homework Equations


No air resitence
Gravity is in effect

The Attempt at a Solution


If I was from the ground the equation would look like this

R = 24 m/s^2 sin 2 45* giving me 58.716 meters
----- 9.81 m/s^2

Try the equation d_f = (at^2)/2 + v_i(t) + d_i. Find the time first and then calculate the range.
