When you resolve a vector into two perpendicular components, you are:

• Combining the two components

• Separating the vector into its horizontal and vertical parts

• Calculating the magnitude of the vector

• Finding the resultant vector

How do you determine the resultant vector when given two components?

• Subtract the components

• Find the vector's direction using trigonometry

• Calculate the vector's magnitude by adding the values and then find direction

• Head to tail add then find magnitude and direction

The horizontal and vertical components of a velocity vector in projectile motion are:
