SUMMARY
The coefficient of kinetic friction (μk) for a box sliding down a 30° ramp with an acceleration of 1.20 m/s² can be calculated using the equation μk = (gsinθ - a) / (gcosθ). The forces acting on the box include the gravitational force, which can be split into components parallel and perpendicular to the ramp, and the frictional force opposing the motion. By applying Newton's second law and substituting the known values, the coefficient can be determined accurately.
