Two identical 9 N bar magnets rest on a wooden table with a coefficients of static kinetic friction both equal to 0.40. The force exerted between the magnetic poles 20250/x³ N where x is in mm and is the distance between the magnets. The magnets are slowly pushed towards one another until they suddenly jump together is the relative speed with which they collide? The center of magnetism for each m is 6.25 mm from the end.
