Review. The instantaneous position of an object is spec- ified by its position vector leading from a fixed ori- gin to the location of the object, modeled as a parti- cle. Suppose for a certain object the position vector is a function of time given by f = 4î + 3j – 2t k, where r is in meters and t is in seconds. (a) Evaluate d T/dt. (b) What physical quantity does d 7/dt represent about the object?
