Hi, Im working on this question its part of a larger question about dynamic viscosity in thermofluids but its the basic mechanics of friction I forget how to do(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

A block weighing150Nis to be moved atconstant velocity 0.8m/sup an inclined surface with afriction coefficient of 0.27. Determine the force F that needs to be applied in the horizontal direction.

(the elevation of the slope is 20 degrees)

2. Relevant equations

F = μN (i think)

3. The attempt at a solution

Applying the basic equation to find the horizontal force results in F = μN,

0.27 X 150 = 40.5N the force required to overcome the friction move the block (Im not sure if the velocity is required for this part but i mentioned it in case it was)
