Answer:
4 m/s².
EXPLANATION
We use Newton's Second Law of Motion, which states:
- Force (F) equals mass (m) multiplied by acceleration (a).
This is written as a formula: F = m * a
To find the acceleration (a), we rearrange the formula:
- a = F / m
Then, we plug in the given values:
- a = 120 N / 30 kg
Finally, we perform the division:
- a = 4 m/s²
Therefore, the acceleration of the cart is 4 meters per second squared (m/s²).
