**Problem 2:** A \(4.6 \times 10^5 \, \text{kg}\) train is brought to a stop from a speed of \(0.75 \, \text{m/s}\) in \(0.48 \, \text{m}\) by a large spring bumper at the edge of its track. What is the force constant \(k\) of the spring in \(\text{N/m}\)? **Numeric:** A numeric value is expected and not an expression. \(k = \) _______________________
