The net force acting on the cart can be calculated using Newton's second law, $F = ma$, where $F$ is the force, $m$ is the mass, and $a$ is the acceleration. First, we find the mass of the cart by dividing its weight by the acceleration due to gravity, $m = \frac{W}{g} = \frac{15.0\, \text{N}}{9.8\, \text{m/s}^2} \approx 1.53\, \text{kg}$. Then, we use the given acceleration ($0.15\, \text{m/s}^2$) to find the net force: $F = ma = 1.53\, \text{kg} \times 0.15\, \text{m/s}^2 = 0.2295\, \text{N}$, which rounds to $0.23\, \text{N}$.
