If it is moving to the left, the frictional force is pushing right.
0.6 * 90 * 9.81
yes, looks about right but stick to 3 significant figures.
A ninety kilogram sofa is being pushed by four meters to the other side of a hall. After an initial push the sofa is pushed with a 600 N force. In this case, 0.6 is the coefficient of kinetic friction. What would be the magnitude and direction of the frictional force on the sofa?
Is this 529.74? The diagram shows the sofa being pushed toward the left, so is the direction of the frictional force to the right?
