A 18.5 kg ball is thrown at an angle of 49° above the horizontal off of a building such that its initial potential energy is 449 J, and the initial kinetic energy is 458 J.

Once the ball is flying in its arc, what will be the potential energy of the ball when the kinetic energy is 71.1 J?

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.
