You are flying a hang glider at 14 mph in the northeast direction (45°). The wind is blowing at 4 mph from due north. a) What is your airspeed?
b) What angle (direction) are you flying?
c) The wind increases to 14 mph from the north. Now what is your airspeed and what direction are you flying? If your destination is to the northeast, how would you change your speed or direction so you might make it there?

a) 17.05 mph

b) 54.7°  northeast direction

c) 10.71 mph

The direction is -22.58° relative to the east.

To head northeast, you must either increase your gliding speed or increase your angle relative to the x-axis greater than 45°.

Explanation:

The question is a little confusing but, I guess the correct question should be;

You are flying a hang glider at 14 mph in the northeast direction (45°). The wind is blowing at 4 mph due north.

a) What is your airspeed?

b) What angle (direction) are you flying?

c) The wind increases to 14 mph from north. Now what is your airspeed and what direction are you flying? If your destination is to the northeast, how would you change your speed or direction so you might make it there?

NB: The difference in the question and my suggestion is highlighted boldly.

Your speed = 14 mph

direction is 45° northeast

Th wind speed = 4 mph

direction is north

We resolve the your speed and the wind speed into the horizontal and vertical components

For vertical the component component

= 14(sin 45) + 4 = 9.89 + 4 = 13.89 mph

For the horizontal speed component

= 14(cos 45) + 0 = 9.89 + 0 = 9.89 mph

Resultant speed =

==> = 17.05 mph  This is your airspeed

b) To get your direction, we use

tan ∅ = /

tan ∅ = 13.89/9.89 = 1.413

∅ = (1.413) = 54.7°  northeast direction

c) If the wind increases to 14 mph from the north, then it means the wind blows due south. As before, only the vertical component is affected .

In this case,

= 14(sin 45) - 14 = 9.89 - 14 = -4.11 mph

Resultant speed =

==> = 10.71 mph  This is your airspeed

Your direction will be,

tan ∅ = /

tan ∅ = -4.11/9.89 = -0.416

∅ = (-0.416) = -22.58°  this is the angle you'll travel relative to the east.

To head northeast, you must either increase your gliding speed or increase your angle relative to the x-axis greater than 45°.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
