1. The velocity v of a falling object (ignoring air resistance) is directly proportional to the time t of the fall. If, after 2 seconds, the velocity of the object is 64 feet per second, what will its velocity be after 3 seconds?

2. A carpenter is building a shelving system and cuts a 14-foot long of cherry, shelving into three pieces. The second piece is twice as long as the first, and the third piece is 2 feet longer than the first. Find the length of each piece of cherry shelving
