SOURCE: trig and distance

Debs,

this is solved by starting with the SECOND leg of the flight considered as a triangle.

Find how far DUE east the plane travels (100 km x Cos10 = 83.9 km) using 10 degrees because that is how much is left of the 90 degree quadrent after subtracting the 80 degrres course direction.
Similarly find out how far DUE north the plane travels (100 km x Cos80 = 11 km).

Now get the total flight NORTH = 300 + 11 = 311
- and total EAST = 83.9

Finally, use Pythagoras theorem.to get the total DISTANCE:
square root of ( 311 squared + 83 squared ) = 321 km

Also the DIRECTION from its Tangent of 83 /311 = 14.9 degrees

SOURCE: compass is no longer pointing North

I had the same issue. I found that if you re-calibrate the compass the same way you did the first time, then it will act properly. I've had to do this a couple of times and it works.

SOURCE: a person walks 25.degree north

(r, theta) --> (3.10 km, 25 degrees)
[r = 3.10 km; theta = 25 degrees]
x = rcostheta
y = rsintheta

x, in this case, would be the horizontal, or eastward distance, so the appropriate values would be substituted in the x equation to solve for it.
x = 3.10 * (cos25) = 2.81 km
y would be the vertical, or northward distance, so the appropriate values would be substituted in the y equation to solve for it.
y = 3.10 * (sin25) = 1.31 km

To verify the solutions, here is the optional step: (just to be sure!)
r = sqrt (x^2 + y^2)
r = sqrt (2.81^2 + 1.31^2)
r = 3.0999 --> 3.10 km

Therefore, the person must walk 1.31 km due north and 2.81 km due east to arrive at the same location.

Vectors in two dimension,how do i approach them?


Just add the three vectors together. The first vector is 0.0i + 4.0j . The second vector is about 1.4i - 1.4j . The third is about -0.7i - 0.7j .

Adding the three vectors together gives about 0.7i + 1.9j .The exact answer is sqrt(0.5)i + (4.0-3sqrt(0.5))j .

A person walks 25.degree north of east for 3.10 km.How far would she have to walk due north and due east to arrive at the same location?


3.10 km times sine of 25 degrees is about 1.31 km.
3.10 km times cosine of 25 degrees is about 2.81 km.
The person would have to walk 1.31 km north and 2.81 km east.

Since you didn't specify the make and model of your calculator, I'm afraid I can't give you the keystroke sequences to calculate these results.

An ant carries food at a speed of 1 cm/s. How long will it take the ant to carry a cookie crumb from the kitchen table to the ant hill, a distance of 50 m? Express your answer in seconds, minutes and...


Since there are by definition 100 cm in a meter, the distance is 50x100 or 5000 cm. At 1cm/s it takes the ant 5000 seconds to cover the distance. There are 60 seconds in a minute, so it takes 83 minutes and 20 seconds.

Agasta ant starts at one edge of a placemant, 29.6 cm wide. she travels at 1.40 cm/sec at 52.o degree from one edge. how long will it take her to get across the width?


draw a right triangle. The bottom of the triangle is 29.6 cm and the angle is 52 degrees (from the other edge). note: triangle not to scale.

| \
|52 \
| \
| \
| \ |
|_____38\ 52|
29.6

Therefore the inside of the angle is 38 (90-52) and the opp angle is also 52 (90-38)

sine = opp / hyp therefore hyp = opp / sine

length of hypotenuse is: 29.6 * sine 52 deg.

therefore the length of the hypotenuse is 23.32511 cm. the ant travels 1.4 cm / sec so the ant travels to the other edge in 16.66 seconds.
