Two students are pushing a box along the ground, but the level of friction is making it very difficult. One of the students suggests the rotate the box so that it is sliding on its largest side, thus "spreading out the friction." Will this student's suggestion help the box slide more easily? Why or why not?

Respuesta :

Answer:

NO

Explanation:

While the normal force per unit area will be decreased, the increased area will exactly compensate for the decreased force per unit area resulting in exactly the same friction resistance.

A better result would be obtained if a rope was use to pull the load at an upward angle from horizontal. The upward force applied would decrease the normal force of the ground on the box and therefore also the friction force.
