Answer 1

To calculate the acceleration of the mass, we can use Newton's second law of motion, which states:

\[ F = ma \]

Where:
- \( F \) is the net force (in newtons)
- \( m \) is the mass (in kilograms)
- \( a \) is the acceleration (in meters per second squared)

Rearranging the formula to solve for acceleration (\( a \)) gives us:

\[ a = \frac{F}{m} \]

Given:
- \( F = 30 \, \text{N} \)
- \( m = 20 \, \text{kg} \)

Substituting in the values:

\[ a = \frac{30 \, \text{N}}{20 \, \text{kg}} \]
\[ a = 1.5 \, \text{m/s}^2 \]

So the acceleration of the mass is \( 1.5 \, \text{m/s}^2 \).

Thus, the correct response is:

**1.5 the fraction with numerator m and denominator s squared**
