Final answer:
To calculate the component of the force that is perpendicular to the momentum, resolve both the force and momentum into their respective components and take the dot product.
Step-by-step explanation:
Momentum is a vector quantity that can be expressed as a sum of perpendicular components. In order to calculate the component of the force that is perpendicular to the momentum, we need to resolve both the force and the momentum into their respective components. The component of the force that is perpendicular to the momentum can be calculated by taking the dot product of the force component and the perpendicular momentum component.
