Can you help me with this force question

[From: ] [author: ] [Date: 11-11-12] [Hit: ]
4.5. 0.05-2. 0.2 F=ma and F=µR constant velocity again.......
A horizontal force of 100 N is used to pull a crate, which weighs 500 N, at constant velocity across a horizontal floor.
What is the coefficient of kinetic friction?

1. 20
2. 0.2
3. 0.5
4. 2
5. 0.05

2. 0.2 F=ma and F=µR constant velocity again. So µR=100N where R=500N therefore U=1/5
