B3-SCT86: Box PULLED ON ROUGH, HORIZONTAL SURFACE-FRICTIONAL FORCE ON BOX
A 100 N box is initially at rest on a rough, horizontal surface. The coefficient of
static friction is 0.6, and the coefficient of kinetic friction is 0.4. A constant 35 N
horizontal force to the right is applied to the box. Four students are discussing the
frictional force exerted on the box by the rough surface 1 second after the force is
first applied:
35 N
100 N
Al:
"The frictional force is 60 N since the box will not be moving and the
coefficient of static friction is 0.6 with a normal force of 100 N."
"The frictional force is 40 N since the coefficient of kinetic friction is 0.4 and there is a normal force
Brianna:
of 100 N."
Carlos:
"The frictional force is 35 N since the box will not be moving and the frictional force will cancel out
the applied force of 35 N.
"It is 40 N for the kinetic frictional force and 60 N for the static frictional force. The normal force is
100 N and the coefficient of kinetic friction is 0.4, giving 40 N for the kinetic friction. Similarly, for
the static frictional force it is 60 N since it has a coefficient of static friction of 0.6."
