During super bowl weekend, the NFL sets up a receiver on a stationary hovercraft. A .257 kg football is thrown at 9.76 m/s to a receiver and hovercraft with a total mass of 98.6 kg. When the ball is caught what is the new speed of the system? Do NOT put in units or it will be marked wrong! The answer's value only! Please round each answer to 3 places.

MaVa + MbVb = (Ma+b)(Va+b)

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.

What is friction? how does it affect the motion of an object?
