Question

Help

Answer 1

The velocity of a ship on a heading 157 degrees has magnitude 35.2 km/hr. The water current has a velocity of 8 km/hr in the direction 213 degrees. Find the magnitude of the actual velocity of the ship. Find the course of the ship.

@HackberryAbby18 @wwhitlock @Surana can yall help her if ur good at math?

Answer 3

@MathGum

Answer 4

Unfortunately, this isn't something I can do. Sorry.

Answer 5

I'd subtract 6 from 35.2 and hope the degree think worked itself out. You probably don't want to be on a boat where I'm navigating though.

Answer 6

So that won't help me find the answer?

Answer 7

You need to add the two vectors you're given in the question to figure out the resultant vector. To do that, follow these steps:

STEP #1: SKETCH OUT THE SITUATION! This will let you get your bearings and figure out exactly how to proceed.

STEP #2: Decompose each given vector into "horizontal" and "vertical" components. You can do this using simple trigonometry. Adding the individual horizontal and vertical components together will give you the corresponding components of the resultant vector.

STEP #3: Add these two vectors (using the Pythagorean Theorem) to find the magnitude of the resultant vector. To find the angle of the resultant vector, just use trig again!

If you have any questions let me know!

Answer 8

I'm really not sure where to start or how to draw it. Would it be a triangle?
