How do you find the y-component of a vector if you are not given the magnitude of the vector?

It depends on what other information you are given. If you are given the x-component and the angle, then you can still use trig by doing the following.
Tan(angle)=y/x
If you do not have the x component, then you will need to use other kinematic equations to find the answer. The different ways to find this information are too numerous to list out, but I will give an example of a common one.
If you are given the horizontal distance and time the object flies, use
d=vt
to find the x component of velocity, then use the first strategy.

How do you find speed given a vector?
Given a vector, speed is the magnitude of the velocity vector, |v|. Consider vector V= IVx + JVy + KVz the magnitude is |V| = ( Vx2 + Vy2 + Vz2)1/2
How do you find vector components when given the vectors are parallel and the magnitude of each vector is equal to 1?
If they are parallel, you can add them algebraically to get a resultant vector. Then you can resolve the resultant vector to obtain the vector components.
How do you find the y-component of a vector if you are given the magnitude?
The magnitude alone can't tell you anything about its components. You also need to know its direction.
When vector is divided by its own magnitude you find its?
We get the Unit Vector
How do you find a vector if you have itsmagnitude and its direction given?
That's it! You know everything there is to know about it. It's not as if you have to wander through a crowd of vectors and find one that matches the description. "Find the vector" means figure out its magnitude and direction. If the problem already gave you the magnitude and direction, then it's unlikely that it's asking you to 'find' that same vector.
How can you find a unit vector in the same direction as the given vector?
Divide the vector by it's length (magnitude).

What does it mean to find the magnitude of a vector?
The magnitude of a vector is a geometrical value for hypotenuse.. The magnitude is found by taking the square root of the i and j components.
How do you find the magnitude and the direction of a vector?
Use trigonometry.
How do you find the vector components only given the magnitude and angle?
One component = (magnitude) times (cosine of the angle).Other component = (magnitude) times (sine of the angle).In order to decide which is which, we have to know the angle with respect to what.
How do you find the vector components only given the magnitude and x-component?
If you assume the vector is only in two dimensions, you can find the missing y-component with Pythagoras' Theorem: y = square root of (magnitude2 - x2).
How do you find the magnitude of a vector?
The magnitude of a vector can be found by taking the square root of each of the vector components squared. For example, if you had the vector 3i+4j, to find the magnitude, you take sqrt ( 3²+4² ) To get: sqrt ( 9+16 ) sqrt ( 25 ) = 5 Works the same in 3D or more, just put all the vector components in.
How to find the direction of vector when the magnitude is given?
You can't derive the direction only from the magnitude. A vector with the same magnitude can have different directions. You need some additional information to make conclusions about the direction.You can't derive the direction only from the magnitude. A vector with the same magnitude can have different directions.
