SUMMARY
The discussion focuses on calculating the coefficient of kinetic friction for a wooden crate being pushed with a horizontal force of 30.0 N. The crate has a mass of 12.0 kg, and the gravitational acceleration is 9.8 m/s². The force of friction is confirmed to be equal to the applied force of 30.0 N, as the crate moves at a constant velocity, indicating that the net force is zero. The coefficient of kinetic friction (μk) can be calculated using the formula Ff = μk * FN, where FN is the normal force.
