The plane will end up flying 5.02°.
The plan's speed relative to the ground will be 645.91 km/hr.
Solution:
Use the cosine formula,
Substitute the given values in the formula,
Taking square root on both sides, we get
R = 645.91 km/hr
This is the grouped speed of the aircraft.
To find θ use sine rule.
Do cross multiplication, we get
sin θ = 0.0875
θ = 5.02°
This is known as the drift angle and is the correction the pilot should apply to remain on course.
The heading is the direction the aircraft's nose is pointing which is
The track is the actual direction over the ground which is θ = 5.02°
An alternative method to this would be to separate each vector into vertical and horizontal components and add.
The resultant can be found using Pythagoras.
Answer: Each donor donated $70.5 per lap.
Step-by-step explanation:
1. If she got 8 donors and each one of them sponsored 5 laps, then the total number of laps was:
laps
2. Hailey raised a total of $2,820, therefore, you can calculate the amount of money donated by each donor (which you can call ) by dividing $2,820 by 40 laps, as you can see below:
