Question: The instantaneous position of an object is specified by its position vector r leading from a fixed origin to the location of the point object.

The instantaneous position of an object is specified by its position vector r leading from a fixed origin to the location of the point object. Suppose that for a certain object the position vector is a function of time, given by r = 4ˆi + 3ˆj 2─tˆk, where r is in meters and t is in seconds. Evaluate dr/dt. What does it represent about the object?
