Review. The instantaneous position of an object isspecified by its position vector leading from a fixedorigin to the location of the object, modeled as a particle.Suppose for a certain object the position vector isa function of time given by rS5 4 i^ 1 3 j^ 2 2t k^ , whererSis in meters and t is in seconds. (a) Evaluate d rS/dt.(b) What physical quantity does d rS/dt represent aboutthe object?
