4. Paul is pushing the couch up the ramp into the moving truck at a CONSTANT VELOCITY. If he pushes with a force of 241 N directly to the right (NOT AT ANY ANGLE), what is the coefficient of kinetic friction

The coefficient of kinetic friction between the couch and the ramp is 0.68.

The given parameters;

The net force on the couch is calculated as follows;

where;

At constant velocity, the acceleration of the couch = 0

Thus, the coefficient of kinetic friction between the couch and the ramp is 0.68.

"Your question is not complete, it seems to be missing the following information;"

Paul is pushing the couch up the ramp into the moving truck at a CONSTANT VELOCITY. If he pushes with a force of 241 N directly to the right (NOT AT ANY ANGLE), what is the coefficient of kinetic friction? The mass of the couch is 36.3 kg.

Explanation:

Complete question:

Paul is pushing the couch up the ramp into the moving truck at a constant velocity. If he pushes with a force of 241 N directly to the right (NOT AT ANY ANGLE), what is the coefficient of kinetic friction? The mass of the couch is 36.3 kg, and the angle of the ramp is 21.5°.

Since the velocity is constant, the acceleration is zero.

Take the sum of the force along the plane according to Newton's second law:

Given

Hence the coefficient of kinetic friction 0.394
