A 6-column table with 2 rows. The first column labeled number of washers has entries 1, 3. The second column labeled Mass of Washers m subscript w (grams) has entries 4.9, 14.7. The third column labeled Mass of Washers m subscript w (kilograms) has entries 0.0049, empty. The fourth column labeled Acceleration due to Gravity a subscript g (meters per seconds squared) has entries empty, 10. The fifth column labeled Force of gravity on the washers F subscript g (kilograms times meters per second squared) has entries 0.049, 0.147. The sixth column labeled Applied force of washers on the car F subscript w c (Newtons) has entries 0049, empty.
The acceleration due to gravity for any object, including 1 washer on the string, is always assumed to be
m/s2.

The mass of 3 washers, when converted to kg, is
kg.

The applied force of 3 washers will increase the applied force on the car to
N.
