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?

FBD helps a lot to solve the problem easily and to get the correct idea of the problem.

'The normal reaction by the readers will defintely balance the weight of your post and We will be in equilibrium'

Haha. Jk :)
Indeed nice post!

Haha. Thank you splash-of-angs63. Glad you liked it.
