Question

An airplane travelling 250 mph is descending at an angle of depression of 5 degrees. How many miles will the plane descend in 3 min?

Answer 1

Can you find the component of velocity in vertical direction ??

Answer 2

Velocity( 3mins) ?

Answer 3

"How many miles will the plane descend in 3 min?"
Find the velocity vector in vertical direction and multiply it with time
or
Calculate the net displacement and find its component in the vertical direction.

Your choice :)

Answer 4

@LastDayWork pls teache me how

Answer 5

First tell me which method will you prefer ??

Answer 6

Find the velocity vector in vertical direction and multiply it with time

Answer 7

(250) x 3? = 750 @LastDayWork

Answer 8

In general, a vector can be resolved into its components like this -

Answer 9

Where V can be any vector

Answer 10

what will happen next?

Answer 11

"How many miles will the plane descend in 3 min?"
=Vsin(x) * time

Make sure that you use consistent units; so first convert 3min into hour

Answer 12

0.05 hr

Answer 13

@LastDayWork what is V(Sin)X ?

Answer 14

v = 250 mph
x = 5°
You need a calculator to get the value of sin(5°)

Answer 15

@Faye281
Can you tell me the final answer now ??

Answer 16

21.79 is the answer

Answer 17

1.1 is the final answer?

Answer 18

Yep, 1.1 is correct
donno where did 21.79 came from..

Answer 19

that is the final answer? but how about V(cos)x * time?

Answer 20

"V(cos)x * time" will give you the distance it traveled in the horizontal direction.

Answer 21

12.5 is the answer?

Answer 22

Answer of this question is 1.1 miles

Answer 23

distance it traveled in the horizontal direction = 12.5 miles

Answer 24

that's all?

Answer 25

Were you looking for something complex ?? :P

Answer 26

haha, thank you very much :)

Answer 27
