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 force applied (in Newtons)
- \( m \) is the mass (in kilograms)
- \( a \) is the acceleration (in meters per second squared)

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

We can rearrange the formula to solve for \( a \):

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

Substituting in the values:

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

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