A force of 25N pushes an object at an angle of mass 50kg at an angle 40 degrees to the horizontal. Calculate the coefficient of friction

What is the acceleration of the object?

Explanation:

If the object is in equilibrium, the coefficient of friction will be -0.772, which is not possible. Thus, a force of 25N cannot push a particle of mass 50kg up a slope of 40 degrees. it's just not large enough of a force.
