A train moves from rest and stops at a station in 20 minutes. For the first 5 minutes, the trains moves with constant acceleration of 0.08m/s²
Its speed remains constant untill a braking force is exerted to stop st .
The time of braking is 12 minutes. calculate the maximum speed of the train.

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.
