Please make sure this is right!!! Mechanic Physics: 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 2.8 kg, encounters a coefficient of kinetic friction μL = 0.34 and slides to a stop in distance dL = 0.41 m. Piece R encounters a coefficient of kinetic friction μR = 0.44 and slides to a stop in distance dR = 0.45 m. What was the mass of the block?
