A box of SOkg is siding at a CONSTANT VELOCITY, It experiences a frictional force of 30 N . What is the co-eficient of miction. A. 0,102 B. 1 C. 30 N

To find the coefficient of friction (μ), we use the formula: frictional force (F_f) = μ * normal force (N). In this case, the normal force is equal to the weight of the box, which can be calculated as the mass (m) multiplied by the gravitational acceleration (g ≈ 9.81 m/s²). Therefore, for the 50 kg box, the normal force is 50 kg * 9.81 m/s² = 490.5 N. Now, substituting the known values: 30 N = μ * 490.5 N, giving μ = 30/490.5 ≈ 0.061. So, the coefficient of friction is approximately 0.061, which means none of the options provided are correct! To visualize this practically, think about sliding a heavy box across a kitchen floor! When you're pushing it with constant effort but still feel it tugging back due to friction, you're experiencing this concept firsthand. The coefficient of friction can change based on the surface, so whether it's wood, tile, or carpet, keep your shoes on, because friction is always at play assisting (or resisting)!
