# AP Physics with Hansenator - Forces in 2-Dimension with Hansenator

Hello Steemians! Another lesson following up from last night.

## Forces in 2-Dimensions

###### Example 1

A 22-kg box lays on a ramp with incline 28 degrees (on Earth). What is the acceleration of the box?

- Always draw a model and free body diagram with forces that include the force of gravity (Fg and break it up into components Fgx and Fgy), the normal force, and friction if the problem states it.
- Fgy and FN are balanced since the box is not falling through the ramp.
- Since the only force in the x-direction is Fgx, that is our net force.

###### Example 2

The several forces below affect the object in the middle. What is the net force vector?

## With Friction

###### Example 1

A box laying on a flat surface with mass 10 kilograms is pushed to the right with a force of 100 N. If there is a kinetic friction coefficient of .11, what is the acceleration?

###### Example 2

A 22-kg box lays on a ramp with incline 28 degrees (on Earth). What is the acceleration of the box if there is a kinetic friction of .2?

Indeed nice post!
