Illustrate what is the coefficient of static friction

Reference no: EM13114839

A 523 kg bear grasping a vertical tree slides
down at constant velocity. The acceleration of gravity is 10 m/s2 . What is the friction force that acts on the
bear? Answer in units of N.

A 29 kg chair initially at rest on a horizontal floor requires a 365 N horizontal force to set it in motion. Once the chair is in motion, a 325 N horizontal force keeps it moving at a constant velocity. The acceleration of gravity is 9.81 m/s2 .

a) What is the coefficient of static friction between the chair and the floor?

b) What is the coefficient of kinetic friction between the chair and the floor?
