What object oriented feature can we use to have a single test program, with one set of method calls in which the user can decide which bag implementation (array - or link-based) needs testing?

What might motivate someone to study forensics

A roller coaster at an amusement park has a dip that bottoms out in a vertical circle of radius r. A passenger feels the seat of the car pushing upward on her with a force equal to five times her weight as she goes through the dip. If r = 17.
