Pauline needs to measure the sliding friction of a brick. How should she go about doing this?

• attach the brick to a string and then to a spring scale and read the force needed to quickly lift the brick off the ground
• drag the brick by a string attached to a spring scale along the surface of a table at a constant speed and read the force
• drag the brick by a string attached to a spring scale so that it gradually speeds up
• hang the brick from a string attached to a spring scale and read the force
