Foundation Mechanics Question involving a body on a plane

", "licence": "Creative Commons Attribution 4.0 International"}, "statement": "

A motor (M) shown in the figure exerts a constant force of {Fm}N on the cable causing the crate of mass {mass_Crate} kg to move up the slope by 10 m. 

\n

The angle of the slope is:  {Ang_Slope}°

\n

The coefficient of friction between the crate and the plane is μ = {Coeff_Fric}

\n

Acceleration due to gravity = {Acc_Grav}ms-2
