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
\(\mathbf{r}(t)=t^{2} \mathbf{i}+t \mathbf{j}\) (4, 2)
Text Transcription:
r(t)=t^2 i + tj
