Newton's 2nd Law: Static and Kinetic Friction. Level 1, Example 1
A 250-kg crate is at rest on a horizontal floor. A horizontal force of just over 980 N is required to make it move and a force of 490 N is required to keep it moving at constant velocity. Calculate μs and μk, the coefficients of friction between the crate and the floor.
