The vector A -5.2 has a magnitude of 38m and points in the positive x direction.
What is the x component of vector A?
What is the magnitude of vector A?
To find the x component of vector A, you can use the definition of a vector as the combination of its components. Since the vector A points in the positive x direction, its x component will have a positive value.
To calculate the x component, we need to determine the value of A in the x direction. Given that the magnitude of vector A is 38m and it points in the positive x direction, we can set up the equation:
|A| = √(Ax^2 + Ay^2)
Since vector A only has an x component, we can ignore the y component (Ay=0). The equation becomes:
|A| = √(Ax^2)
Solving for Ax:
Ax = √(|A|^2) = √(38^2) = √1444 = 38
Therefore, the x component of vector A is 38m.
To find the magnitude of vector A, you can use the Pythagorean theorem. The magnitude of a vector is equal to the square root of the sum of the squares of its components.
Therefore, the magnitude of vector A is given as 38m.
It is in the +x direction.
