Question

Required information

A 770-kg block is at rest on a horizontal floor. If you push horizontally on the 770-kg block with a force of 12.0 N, it just
starts to move.
What is the coefficient of static friction?
only Numeric Response please

Answer 1

Let μ s be the coefficient of static friction between the block and the floor.

F=μ s mg

We get μ s = F/mg

​∴ μ s = 20/ 8×9.8 =0.255
