Question

Mariah and Caitlyn are moving a sofa for their teacher. If the sofa weighs 350 kg, how fast did the sofa accelerate if a 48 N force was applied?

Answer 1

`7.291(6)(m)/(s^2)`

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?)

`a = (F)/(m)\\a = (350kg)/(48N) = (350kg)/(48(kg\cdot m)/(s^2)) = (350)/(48)(m)/(s^2) = 7.29166666\ldots(m)/(s^2)`
