In a scene in an action movie, a stuntman jumps from the top of another building that is 4.0 m away. after a running start, he leaps at a velocity of 5.0 m/s at an angle of 15 degrees with respect to the flat roof. how far will he fall?

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.
