Need help on displacement asap

In summary, the conversation is about three different problems involving angles and distances. The first problem involves a submarine diving at an angle of 28 degrees below the horizontal and finding its two components. The second problem involves a person walking at a specific angle and distance, and determining the distance needed to walk due north and due east to reach the same location. The third problem involves a guy walking on a path with four straight line paths, each with different distances and angles. A helpful resource is provided for further assistance.

Hi PF! Okay so here's a problem I'm having trouble with.

A- A submarine dives 104 m at an angle of 28 degrees below the hor. . What are the two components (x & y)

B- A person walks 23 degrees north of east for 2. 38 km. How far woud another person walk due north and due east to arrive at the same location.

C- 5. A guy walks the path shown below. The total trip consists of four straight line paths.
Path 1 is 60.0 m due east.
Path 2 is 220.0 m due south.
Path 3 is 130.0 m 30.0° south of west.
Path 4 is 150.0 m 60.0° north of west.

Please helpp

Hi claire! Welcome to PF! :smile:

Three problems, actually! :wink:

Show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:
 

1. What is displacement?

Displacement is a measurement of the distance and direction between an object's starting point and its ending point. It is often represented by an arrow pointing from the starting point to the ending point.

2. How is displacement different from distance?

Distance is a measurement of how far an object has traveled, while displacement takes into account the direction of the movement. For example, if an object moves 5 meters to the east and then 5 meters to the west, its distance traveled would be 10 meters, but its displacement would be 0 meters.

3. What are the units of displacement?

Displacement is typically measured in units of length, such as meters, centimeters, or kilometers. The specific unit used will depend on the context and scale of the displacement being measured.

4. How is displacement calculated?

Displacement can be calculated by subtracting the initial position from the final position of an object. This can be represented mathematically as Δx = xf - xi, where Δx is the displacement, xf is the final position, and xi is the initial position.

5. Why is displacement important in science?

Displacement is important in science because it allows for the accurate measurement and tracking of an object's movement. It is a fundamental concept in physics and is used in many fields, including mechanics, kinematics, and fluid dynamics.
