To find the acceleration of the object, we can use Newton's second law of motion, which states that:
\[ F = ma \]
where:
- \( F \) is the force applied (in Newtons),
- \( m \) is the mass of the object (in kilograms),
- \( a \) is the acceleration (in meters per second squared).
We can rearrange the formula to solve for acceleration:
\[ a = \frac{F}{m} \]
Given:
- \( F = 53 , \text{N} \)
- \( m = 11 , \text{kg} \)
Now, substituting the values:
\[ a = \frac{53 , \text{N}}{11 , \text{kg}} \]
\[ a = 4.8181 , \text{m/s}^2 \]
Rounding it off to one decimal place, the acceleration is approximately:
\[ a \approx 4.8 , \text{m/s}^2 \]
So the answer is 4.8 m/s².
