Question Description

In this discussion, you will post an example showing how vectors are added to form a resultant vector. (The discussion lesson slides talk about errors, but that will not be required.)

Using what you have learned in this activity, develop a unique example of a vector addition problem. Remember to use the type of things measured by vectors such as displacement, velocity, acceleration and force. Your vectors must be at some angle other than 0 or 180 degrees. Include the write-up of your example along with an answer key. A diagram would be helpful though not required as long as you are very clear in your write-up. Remember to include both direction and magnitude in your answer. (20pts)

Science | Graded Assignment | Lab Report for Discussion Name: Date: Graded Assignment Lab Report for Discussion Answer the following questions before you participate in the discussion. Note: You will not turn in this report to your teacher. 1. A man pulls a crate with a rope. The crate slides along the floor in the horizontal direction (x direction). The man exerts a force of 50 N on the rope, and the rope is at an angle θ . Describe how the force components (Fx , Fy ) change as the angle increases from 0° to 90° and use your graph to explain your answer. Give a detailed explanation of the forces at  = 0,45,and90 . Show a sample calculation at one angle for both components. Answer: Fx = r*Cos(q) Fy = r*Sin(q) Fx = 50*Cos(0) = 50 N Fy = 50*Sin(0) = 0 N Fx = 50*Cos(45) = 35.355 N Fy = 50*Sin(45) = 35.355 N Fx = 50*Cos(90) = 0 N Fy = 50*Sin(90) = 50 N 2. A plane flies due north (90° from east) with a velocity of 100 km/h for 3 hours. During this time, a steady wind blows southeast at 30 km/h at an angle of 315° from due east. After 3 hours, where will the plane’s position be relative to its starting point? Show your work. Answer: Type your answer here. © 2015 K12 Inc. All rights reserved.

Where is the final destination, and what is its displacement from New Orleans? Show a data table containing each vector and its x and y components. Include the values of dnetx , dnety , dnet , tan r , and r . Answer: Type your answer here. Instructions for the Discussion: Design your own vector addition problem similar to the practice ones you did as part of this lab. Post your problem along with a detailed answer key showing how to solve it. Be sure your example is unique! Once you have posted your problem, check over at least 2 posted by class mates. Respond by confirming or refuting their solution with an explanation. © 2015 K12 Inc. All rights reserved. Copying or distributing without K12’s written consent is prohibited. Page 2 of 2 ...
