"addition and subtraction"
Resultant velocity refers to the sum of all vectors in an equation. The two math functions that are used to calculate the resultant velocity are addition and subtraction.
Equation: Force=Mass X Acceleration
If you are looking for the force, use the equation as is.
To find the following, it's assumed that you are given the other two values:
Mass= Force / Acceleration
Acceleration= Force / Mass
Remember your labels in your calculations.
Mass= force x acceleration
Force = mass x acceleration
mass = force / acceleration
acceleration = force / mass
