In the figure here , a stationary block explodes into two pieces L and R that slide across a frictionless floor and then into regions with friction , where they stop . Piece L , with a mass of 4.0 kg, encounters a coefficient of kinetic friction mu 1 =0.58 and slides to a stop in distance d L =0.40 m . Piece Rencounters a coefficient of kinetic friction mu R =0.44 and slides to a stop in distance d R =0.44 m . What was the mass of the block?

the force on the thing and the distance the force moves the thing

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
