Answer 1

To calculate the acceleration of the mass, we can use Newton's second law of motion, which states that \( F = ma \), where \( F \) is the net force applied, \( m \) is the mass, and \( a \) is the acceleration.

Given:
- Mass (\( m \)) = 20 kg
- Force (\( F \)) = 30 N

We can rearrange the formula to find acceleration (\( a \)):
\[
a = \frac{F}{m}
\]

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

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

The correct response is:
1.5 the fraction with numerator m and denominator s squared.
