A helicopter goes straight up 500m from a landing pad. It then goes north 20m. Then it goes down 452m. a) What is the displaceme

gavmur [86]

Answer:

x-component $20 \ m$

y-component $500 - 452 = 48 \ m$

Magnitude $d = 52 \ m$

direction is $\theta = 67.4^o$

Explanation:

From the question we are told that

The first vertical distance is $y_1 = 500 \ m$

The first horizontal distance is $x = 20 \ m$

The second vertical distance is $y_2 = 452 \ m$

Generally the displacement is

x-component $20 \ m$

y-component $500 - 452 = 48 \ m$

Generally the helicopters displacement is mathematically evaluated as

$d = \sqrt{ x- component ^2 + y- component ^2 }$

$d = \sqrt{ 20t ^2 + 48 ^2 }$

$d = 52 \ m$

The direction is the angle the displacement of the helicopter makes with the horizontal which is mathematically evaluated as

$\theta = tan ^{-1}[ \frac{48}{20}]$

=> $\theta = tan ^{-1}[ 2.4 ]$

=> $\theta = 67.4^o$
