Finding Velocity and Acceleration Along a Plane Curve In Exercises 1-8,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 Point
\(\mathbf{r}(t)=2 \cos t \mathbf{i}+2 \sin t \mathbf{j}\) (\(\sqrt{2}, \sqrt{2}\))
Text Transcription:
r(t)=2 cos t i + 2 sin tj
