Answer:
[tex]7.291(6)\frac{m}{s^2}[/tex]
Step-by-step explanation:
Firstly, there's definitely large friction with a sofa, so we cannot answer.
Assming there is no friction:
The acceleration is directly proportional to force and inversely proportional to mass (makes sense, right?)
[tex]a = \frac{F}{m}\\a = \frac{350kg}{48N} = \frac{350kg}{48\frac{kg\cdot m}{s^2}} = \frac{350}{48}\frac{m}{s^2} = 7.29166666\ldots\frac{m}{s^2}[/tex]
