Assuming g is the centroid, it is 2/3 of the length of cf from point c.
cg = (2/3)cf = (2/3)3.6 m
cg = 2.4 m
Answer:
4900
Step-by-step explanation:
You multiply lengthxwidthxheight, all the given dimensions to get (25x14x14) 4900
Answer:
Step-by-step explanation:
This is the kind of problem that is most easily solved graphically, because the solution point coordinates give both the time and the altitude.
The attached graph shows the planes both arrive at the altitude of 7093 feet after 52 seconds.
__
The equations for altitude in feet (y) as a function of time in seconds (x) are ...
y = 3687 +65.5x . . . . . plane A
y = 5000 +40.25x . . . plane B
Subtracting the second equation from the first gives . . .
0 = -1313 +25.25x
x = 1313/25.25 = 52 . . . . . . . add 1313 and divide by the x-coefficient
y = 3687 +65.5(52) = 3687 +3406 = 7093
After 52 seconds both planes have an altitude of 7093 feet.
