A group of students carry out an experiment in which they want to find the coefficient of kinetic friction between a box and a table. For this, a wooden box is used that has a mass of 250 gr and additional masses that are placed on top. The box is pulled and the force at which it moves at constant speed is measured. Determine:
a) The normal force when the box had no masses on top and when masses were placed on top of the box. (Fill in the table below) (You have to show an example of the calculation)
