To calculate: The magnitude to three significant digits and bearings to the nearest tenth of a degree and to find the heading and speed should a plane travel.
A fly due north at
Answer to Problem 4P
The speed and the headingis
Explanation of Solution
Given information:
A fly due north at
Formula used:
The cosine law:
Calculation:
Consider the A fly due north at
North is a direction of
Then wind interior from north is
Now by the low of cosines it is written as:
So it can be written as:
Now solve for
Now apply the values of
By cross multiplication:
Thus, the speed and heading is
