What is the role of the normal force in this problem?

• It opposes the frictional force

• It cancels out the force of gravity

• It adds to the applied force

• It accelerates the cabinet

What is the significance of the net force being zero in the y-axis?

• The cabinet is moving horizontally

• There is no vertical acceleration

• The cabinet is accelerating upward

• The cabinet is accelerating downward

What is the formula to calculate the net force?

• Force = Mass / Acceleration

• Force = Mass + Acceleration

• Force = Mass x Acceleration

• Force = Mass x Velocity
