# A box having a mass of \( 1.5 \) \( \text{kg} \) is accelerated across a table at \( 1.5 \) \( \text{m/s}^2 \). The coefficient of kinetic friction on the box is \( 0.3 \).

A box having a mass of \( 1.5 \) \( \text{kg} \) is accelerated across a table at \( 1.5 \) \( \text{m/s}^2 \). The coefficient of kinetic friction on the box is \( 0.3 \).

**Part a)** Determine the magnitude of the applied force on the box. *(3 points)*

**Part b)** Given that this force is provided by a spring that stretches only \( 0.08 \) \( \text{m} \) while pulling the box, calculate the required spring constant. *(3 points)*
