In physics, we have the formula ρ = m/v where ρ is density, m is mass, and v is volume. Suppose an object starts with a mass of 2 kg and a volume of 10 cm3 . The object begins to lose mass at a rate of 0.2 kg/s and gain volume at a rate of 1 cm3/s. What is the rate of change of the density when the mass is 1 kg?
