A 2 kg crate is pulled with a force of 54 N along a floor where friction is 30 N. What is its acceleration?
Answer and explanation
Correct answer: B. m/s²
- Step 1: Resultant force N.
- Step 2: m/s².
Answer
m/s².
Why not the others: m/s²: Friction was ignored. m/s²: Friction was added to the pull. m/s²: The force was not divided by the mass.
