Which best describes the friction acting on the piano?
A
The kinetic frictional force is greater than the static frictional force, so the kinetic frictional force is greater than 1200 N.B
The static and kinetic friction are both equal to the gravitational force of 2200 N.C
The static and kinetic frictional forces are equal, so the static frictional force is equal to 1200 N.D
The static frictional force is greater than the kinetic frictional force, so the static frictional force is greater than 1200 N.
