According to Newton's second law of motion:

1.objects at rest will remain at rest unless acted upon by an outside force

2.mass has an inverse relationship with acceleration

3.the greater the magnitude of force, the faster the acceleration

4.acceleration is caused by unbalanced forces

5.every action has an equal and opposite reaction

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.
