Answer:
The velocities after 739 s of firing of each engine would be 6642.81 m/s in the x direction and 5306.02 in the y direction
Step-by-step explanation:
- For a constant acceleration:
, where
is the final velocity in a direction after the acceleration is applied,
is the initial velocity in that direction before the acceleration is applied, a is the acceleration applied in such direction, and t is the amount of time during where that acceleration was applied.
- <em>Then for the x direction</em> it is known that the initial velocity is
5320 m/s, the acceleration (the applied by the engine) in x direction is
1.79 m/s2 and, the time during the acceleration was applied (the time during the engines were fired) of the is 739 s. Then:
- In the same fashion, <em>for the y direction</em>, the initial velocity is
0 m/s, the acceleration in y direction is
7.18 m/s2, and the time is the same that in the x direction, 739 s, then for the final velocity in the y direction:
Given:
In the given ΔXYZ,
Base = 22
Height = 23.1
Also,
Base = 31.9
Height = 15.9
To find the area of the given ΔXYZ.
Formula
The area of a triangle is
where, b be the base and
h be the height.
Now,
Taking, b = 22 and h = 23.1 we get,
sq unit
Again,
Taking,
b = 31.9 and h = 15.9 we get,
sq unit
Therefore,
We can find the approximate area of the triangle by following two expression
a) and
b)
