1. ### Vector as a function of theta

Express the vector \vec{OA} and \vec{AB} as a function av θ. Suppose that the angle between OA and AB is 90°. I have begun to define the unitvector: \underline{e}_{OA}=\begin{bmatrix}-sin\theta\\ -cos\theta\\0\end{bmatrix}\leadsto \vec{OA}=40\begin{bmatrix}-sin\theta\\...
2. ### Year 11 Homework Physics Question (Kinematics)

A model car travelling 4m/s east veers around a rock and 4s later is moving at 6m/s at 50˚ east of north. What was the model car's acceleration?
3. ### Python script to find drag force on a 2D object given differential pressure vectors

I am in need of a python program to calculate the drag force on a 2D object, given differential pressure acting on the object-- this will have to be calculated either manually or (hopefully) by the code. I have the exact location of each pressure vector via a .dat file, and would like to know...

Hi please refer to the image for the question.
5. ### A question regarding vectors and angle between vectors

In my attempt, I got 2 answers √3 and 1 but the solutions say that the answer is only √3. Am I missing something? Sent from my S6 using Tapatalk
6. ### Can only vectors be multiplied in Euclidean Space?

After googling I could see vector product and scalar product in Euclidean Space. But can scalar be multiplied by vector in Euclidean space? If it can then I have a conclusion from the previous post. If so we can conclude that the direction does not change when a scalar is multiplied by vector...
7. ### Retrograde motion of Mars

I have an annoying Physics question that I have been trying to work at for about 3 hours now, the class I'm taking is Calculus based but I'm not even sure if this question is necessarily calculus-related, I'm not sure how I should be approaching it. Here is a link because of the subscripts and...

12. ### My Vectors and Projectile home work

Lab 4 Projectile Motion - Physics 11 Hello Im woking oiin my lab for school and Im having alot of trouble (compare your predicted ranges to the average mesured ranges). So we shot steel ballls off of our desks in class using a bolt with 4 diffrent power settings and calculating inital...
13. ### Vectors

I am having some trouble doing this vectors question and was hoping for some guidance on how to complete it. The question is as follows: Using vector components, find the resultant R for the sum of two vectors A and B shown in the diagram.
14. ### Lever Weight Transfer Vectors

Hi guys, I don't know if this is being posted in the correct location. I am looking for an answer to a question I am having trouble answering. I have a lever transferring the weight to an air cylinder and I am trying to find the angle that the vector is being applied to the pivot points 1...
15. ### coplanar vectors

Under what condition three vectors A, B, C will be co-planar? I want to learn this rules and theorem.
16. ### Viewing vectors

Hello everybody, My name is Vivian. I have been going through vector spaces for quiet long now, but somehow I am unable to visualize a space spanned by N independent vectors. Can someone help me understand it with a simple practical example? More over I have been going through Lagrange's...
17. ### Vectors

I can't solve these questions so please help me 1) Two persons A and B are located in X-Y plane at the points (0,0) and (0,10) respectively.(The distances are measured in MKS units.) At a time t=0 they start moving simultaneously with velocities Va=2 jcap m/s and Vb=2 icap m/s respectively. The...
