370=μ(s)•m•g
μ(s)=370/mg,
μ(k)=332/mg,
A 23 kg chair initially at rest on a horizontal
floor requires a 370 N horizontal force to set
it in motion. Once the chair is in motion, a
332 N horizontal force keeps it moving at a
constant velocity.
The acceleration of gravity is 9.81 m/s
2
.
a) What is the coefficient of static friction
between the chair and the floor?
