That looks good, provided that the applied 24 N force acts parallel to the plane. Since the problem does not specify that, I guess you'll have to assume it.Misr said:
Indeed it does, my errorStonebridge said:
Frictional force is a force that opposes the motion of an object when it comes into contact with another object or surface.
The frictional force can be calculated by multiplying the coefficient of friction (μ) by the normal force (N). In this case, the frictional force of 24 N can be calculated as μN = 24 N.
The normal force is the perpendicular force exerted by a surface on an object that is in contact with it. It is equal to the weight of the object in most cases.
The coefficient of friction can be determined by conducting experiments and measuring the force required to move an object against a surface. It is a dimensionless quantity that varies depending on the materials and surfaces in contact.
The frictional force can be affected by several factors such as the nature of the surfaces in contact, the force pressing the surfaces together, the smoothness of the surfaces, and the presence of lubricants.
