The position vector describes the path of an object moving in the xy-plane.

(a) Find the velocity vector, speed, and acceleration vector of the object.
(b) Evaluate the velocity vector and acceleration vector of the object at the given point.
(c) Sketch a graph of the path, and sketch the velocity and acceleration vectors at the given point.

Position Vector r(t) = 3ti + (t 1)j Point (3,0)
