SUMMARY
A 1.6-kg block sliding down a 25° inclined plane at a constant speed of 2.0 m/s experiences a frictional force that does work on the block. Since the block moves at a constant speed, the net force acting on it is zero, indicating that the frictional force equals the component of gravitational force parallel to the incline. To calculate the rate at which the frictional force does work, one must analyze the forces acting on the block, particularly focusing on the balance of forces along the incline.
