Question

In her lab, Mrs. Smith is pulling a 28 N block across a surface with a constant speed. If

she must pull with a force of 4.0 N, what is the coefficient of sliding friction between the
block and the lab table?

Answer 1

0.14 is the friction coefficient.

Step-by-step explanation:

The equation for the friction coefficient is friction coefficient = force/normal force. The force is 4N, and the normal force is 28N. 4/28=0.14.
