Students in a physics lab design an experiment to determine the coefficient of static friction
between a 1.8-kg jack-o'-lantern and the tabletop on which it rests. Their setup is shown in
the figure below. The basic procedure is to pour sand slowly into the pail until the pumpkin
begins to slide. The pail with the sand in it is then placed on a scale and found to weigh 11 N.
What is the coefficient of static friction between the jack-o'-lantern and the table?
