You are a baseball coach and watch as your star player slides headfirst into second bate, where he
strikes his head against the leg of the second
baseman. He stands up and immediately falls down.
He complains that he cannot get his balance back.
Should you call for an ambulance? Why/Why Not?
What do you think is wrong with him? What is
your reasoning?
PLEASE ANSWER FAST

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.
