1. **Write down Newton's second law of motion:**  
   $$
   F = m \cdot a
   $$

2. **Identify the given values:**  
   $$
   m = 1600\, \mathrm{kg}, \quad a = 4.5\, \mathrm{m/s^2}
   $$

3. **Substitute the given values into the formula:**  
   $$
   F = 1600\, \mathrm{kg} \times 4.5\, \mathrm{m/s^2}
   $$

4. **Perform the multiplication:**  
   $$
   F = 7200\, \mathrm{N}
   $$

5. **Final Answer:**  
   The net force required is $$ 7200\, \mathrm{N} $$.
The net force required is 7200 N.
