what is the units for your answer?
select one:
a. m/s²
b. n
c. kg

Explanation:

Step1: Recall Newton's Second Law

Newton's second law states \( F = ma \), 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 \( F = 29\,\text{N} \) and \( a = 31\,\text{m/s}^2 \). Substitute these into the formula: \( m=\frac{29}{31}\approx0.935\,\text{kg} \).

Answer:

The mass of the ball is approximately \( 0.94\,\text{kg} \) (or more precisely \( \frac{29}{31}\approx0.935\,\text{kg} \)). For the unit question, the correct unit is \( \text{kg} \) (option C. kg).
