Two cars are moving into the same direction, with velocities v01=20 m/s and v02 =10 m/s respectively. When the distance between the cars becomes 100 m, they start decelerating with accelerations of 1 m/s^2 and 3 m/s^2 respectively. Investigate if there is a collision. If YES, after how many seconds will the cars collide? If NO, what is the distance between them after they both have stopped?

An open cart is moving along a straight frictionless horizontal track. when rain starts falling vertically into the cart, what happens to the speed of the cart?

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.
