Vector addition problem needs help

In summary, the conversation discusses the velocity vectors V1 and V2, with V1 having a magnitude of 4m/s and being directed along the +x-axis, and V2 having a magnitude of 3m/s. The sum of the two vectors, V3, equals V1+V2. Based on this information, the statements are all False except for statement B, which is True.

The velocity vector V1 has a magnitude of 4m/s and is directed along the +x-axis. The velocity vector V2 has a magnitude of 3m/s. The sum of the two is V3, so that V3 = V1+V2
(For each statement select T-True, or F-False; If the first is True and the rest F, enter TFFFFF).

A) The magnitude of V3 can be 7m/s
B) The x-component of V3 can be 0m/s
C) The magnitude of V3 can be -4m/s
D) The magnitude of V3 can be 0
E) The magnitude of V3 can be 8m/s
F) The magnitude of V3 can be 3m/s

i hate these tyes of problems can someone please help me out

Tell us what you have tried so far. The math is only addition and subtraction, so your problem begins by finding out what a vector is. You got a textbook?
 

FAQ: Vector addition problem needs help

1. What is a vector addition problem?

A vector addition problem is a mathematical operation that involves combining two or more vectors to find their resultant vector. It is used to represent the magnitude and direction of a physical quantity, such as displacement or force.

2. How do you solve a vector addition problem?

To solve a vector addition problem, you will need to add the components of each vector together. This can be done graphically by drawing the vectors on a coordinate plane and using the parallelogram method, or algebraically by breaking the vectors into their x and y components and adding them together.

3. What are the rules for vector addition?

The rules for vector addition include the commutative property, where the order of vector addition does not matter, and the associative property, where vectors can be grouped and added in any order. Additionally, vectors must be added using the parallelogram or triangle method, and the resultant vector is the diagonal of the parallelogram or the sum of the two sides of the triangle.

4. What is the difference between vector addition and scalar addition?

Vector addition involves adding both the magnitude and direction of a vector, while scalar addition only involves adding the magnitudes of two quantities. Vector addition results in a resultant vector, while scalar addition results in a single value.

5. Can vectors in different dimensions be added together?

No, vectors in different dimensions cannot be added together. In order to add vectors, they must have the same units and be in the same dimension, such as both being two-dimensional or three-dimensional.
