Atennis player receives a shot with the ball (0.0600 kg) traveling horizontally at 25.0 m/s and returns the shot with the ball traveling horizontally at 39.0 m/s in the opposite direction. (assume the initial direction of the ball is in the −x direction.

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.
