**Vector Functions and Motion Along a Curve**

The path **r(t) = ⟨t, (2t² - 5)⟩** describes motion on the parabola **y = 2x² - 5**. Find the particle's velocity and acceleration vectors at **t = 1**, and sketch them as vectors on the curve.

**The velocity vector at t = 1 is v(1) = ⟨[ ], [ ]⟩** *(Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.)*

---

Explanation:

1. **Velocity Vector**: To find the velocity vector, differentiate the position vector **r(t)** with respect to time **t**.
   
   If **r(t) = ⟨t, (2t² - 5)⟩**, then:
   - **v(t)** = d**r(t)**/dt = ⟨1, 4t⟩ 
   
   So, at t = 1:
   - **v(1)** = ⟨1, 4⟩

2. **Acceleration Vector**: To find the acceleration vector, differentiate the velocity vector **v(t)** with respect to time **t**.
   
   If **v(t) = ⟨1, 4t⟩**, then:
   - **a(t)** = d**v(t)**/dt = ⟨0, 4⟩
   
   So, at t = 1, the acceleration vector is:
   - **a(1)** = ⟨0, 4⟩

3. **Sketching Vectors**: When sketching the vectors on the curve, make sure to:
   - Draw the parabola **y = 2x² - 5**.
   - Plot the point corresponding to **t = 1**, which is **(1, -3)**.
   - Draw the velocity vector **v(1) = ⟨1, 4⟩** originating from the point **(1, -3)**.
   - Draw the acceleration vector **a(1) = ⟨0, 4⟩** also originating from the point **(1, -3)**.
