An easy way to visual this is by drawing a triangle with the vectors. Obviously one vector will be the vertical and another will be perpendicular to that, the horizontal. These two vectors will connect at the ends. Then you connect the other two ends with another vector and that is the resultant. Vector sum, or the square root of the sum of the squares; you use the pythagorem theorem to find the resultant, also the hypotenuse.
r2= v12 + v22. The vertical vector squared plus the horizontal squared, you take the root of the sum of the squared vectors and that gives the resultant vector. If the horizontal or vertical vector is negative, then the resultant vector will be negative as well. This is used for any units including velocity, distance, and acceleration.

JudyTo find the resultant velocity from two perpendicular velocities, you can use the Pythagorean theorem. Square each velocity, sum the squares, and then take the square root of the total to find the magnitude of the resultant velocity. The direction of the resultant velocity can be determined using trigonometry, typically with the arctangent function.

Calculate resultant velocity?
To calculate resultant velocity, you would need to determine the magnitude and direction of the individual velocities that are involved. Then, you can use vector addition to find the resultant velocity by adding the velocities together considering both magnitude and direction.
How do you find the distance given only the initial velocity traveled time and final velocity?
You can use the equation: distance = (initial velocity + final velocity) / 2 * time. This formula assumes constant acceleration.
Average velocity always equals one-half the sum of the initial and final velocities?
Average velocity is actually calculated by taking the total displacement and dividing it by the total time it took to cover that distance. The equation to find average velocity is (final velocity + initial velocity) / 2.
How do you find distance with uniform velocity time final velocity and initial velocity?
If the velocity is uniform, then the final velocity and the initial velocity are the same. Perhaps you meant to say uniform acceleration. In any event, the question needs to be stated more precisely.
How do you calculate velocity after perfectly collision?
v2=(m1*v1)/m2 when: v2= velocity after collision m1 = mass before collision v1 = velocity before collision m2 = total mass after collision law of conservation of momentum
