Quizplus · Accepted Answer

The net force on the block is the applied force minus the force of friction and the component of gravitational force parallel to the slope. The frictional force is calculated using the normal force and the coefficient of kinetic friction. The acceleration is found by dividing the net force by the mass of the block.
