Determine the friction force that occurs when the brick moves up the vertical wall, if the friction coefficient is 0.75

Determine the friction force that occurs when the brick moves up the vertical wall, if the friction coefficient is 0.75, and the brick is pressed with a force of 100 N.

These tasks: μ (coefficient of friction of a brick on a vertical wall) = 0.75; F (the force with which the brick is pressed against the wall) = 100 N.

The resulting frictional force when moving the brick taken up the wall is determined by the formula: Ftr = μ * N = μ * F.

Let’s calculate: Ftr = 0.75 * 100 = 75 N.

Answer: When the brick was moved, a friction force of 75 N.
