If the dresser is sliding with a constant velocity, find FFF, the magnitude of the force that the person applies.

Complete Question

The complete question is shown on the first uploaded image

The force is  

Explanation:

Generally the magnitude of the force the person applied is equivalent to the kinetic frictional force acting on the dresser

   So  

         

Here N is the normal force acting on the dresser at point  P and  Q  that is  

     

So

     

Generally this normal force is equal to  the mass of the dresser multiplied by the acceleration due to gravity so

     

Hence
