Physics

We are given:

Mass of the object, ,

Angle of the applied force, ,

Distance moved, ,

Coefficient of kinetic friction, ,

Gravitational acceleration, ,

,

.

 

The object is moving at constant speed, which means the net force in the horizontal direction is zero. Therefore, the horizontal component of the applied force is balanced by the frictional force.

 

Calculate the normal force

The normal force is the upward force that balances the vertical forces on the object. The vertical forces are:

The weight of the object: ,

The vertical component of the applied force: .

 

The normal force is:

 

Calculate the frictional force

The frictional force is given by:
