Explanation:

Step1: Recall Newton's second law

Newton's second law states that \( F = ma \), where \( F \) is force, \( m \) is mass, and \( a \) is acceleration. We need to solve for \( m \), so rearrange the formula to \( m=\frac{F}{a} \).

Step2: Substitute the given values

We know \( F = 350\ N \) and \( a = 10\ m/s^2 \). Substitute these into the formula: \( m=\frac{350}{10} \).

Step3: Calculate the mass

Simplify the division: \( \frac{350}{10}=35 \). So the mass \( m = 35\ kg \).

Answer:

C. 35 kg
