Question
14b.1 Please help me answer all parts to this math problem.
![**Position Function and Motion Analysis**
Consider the position function below.
\[ \mathbf{r}(t) = \langle 1 - t^4, 3 - 2t^3 \rangle \quad \text{for } t \geq 0 \]
**a.** Find the velocity and the speed of the object.
**b.** Find the acceleration of the object.
This problem involves analyzing the motion of an object in two dimensions using the given position function. To solve part (a), differentiate the position vector with respect to time \(t\) to find the velocity vector and then calculate the magnitude to find the speed. For part (b), differentiate the velocity vector to find the acceleration vector.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb3bd88a3-9d65-41d6-8e96-bcf2f13eb11b%2F92ec7c04-0d1b-4eb6-aad3-dbeb2ef1b155%2Fpohbh9s_processed.png&w=3840&q=75)
