### Physics Problem: Dynamics and Kinematics

1. **Tom, the cat, and Jerry, the mouse**  
   Jerry runs past Tom at 10.00 m/s. At the same time Jerry passes Tom, Tom, who was at rest, starts accelerating at 3.00 m/s².
   - **a)** How long does it take for Tom to catch up with Jerry?
   - **b)** What is the velocity of Tom when he catches up with Jerry?
   - **c)** If there was a mouse hole located 2.1 meters away from Jerry when Tom began chasing Jerry, would Jerry make it to the hole without being caught?

2. **Diagram Explanation**  
   The diagram illustrates Tom and Jerry in a chase scenario:
   - **Tom:** Accelerating with a constant acceleration of 3.00 m/s².
   - **Jerry:** Moving with a constant velocity of 10.00 m/s.
   
   Tom is depicted as running towards the right with Jerry ahead of him, also moving toward the right. The visual shows a mouse hole symbolizing Jerry's potential escape route.

### Solution Steps

#### a) Time for Tom to Catch Up with Jerry
Let's denote:
- \( v_j = 10.00 \, \text{m/s} \) (Jerry's constant velocity)
- \( a_t = 3.00 \, \text{m/s}^2 \) (Tom's acceleration)
- \( t \) (time at which Tom catches up with Jerry)
- \( s \) (the distance covered)

Since Jerry moves at a constant speed and Tom starts from rest but accelerates:

For Jerry:
\[ s = v_j \cdot t \]

For Tom:
\[ s = \frac{1}{2} a_t \cdot t^2 \]

Setting the distances equal:
\[ v_j \cdot t = \frac{1}{2} a_t \cdot t^2 \]
\[ 10.00 \, t = \frac{1}{2} \cdot 3.00 \cdot t^2 \]
\[ 10.00 \, t = 1.50 \, t^2 \]
\[ t = \frac{10.00}{1.50} \]
\[ t \approx 6.67 \, \
