A 10 kg crate on a rough horizontal floor is pushed by a horizontal force of 60 N. The coefficient of kinetic friction is 0.5. Taking m/s, find the acceleration.
Answer and explanation
Correct answer: C. 1.1 m/s
- Step 1: Friction N.
- Step 2: m/s.
Answer
1.1 m/s.
Why not the others: 6 m/s: friction is ignored. 10.9 m/s: friction is added instead of subtracted. 11 m/s: the net force is not divided by the mass.
