Normal Force on an Object at the Bottom of a Pool


A child throws a toy car of a mass of $0.030 \space kg$ in a swimming pool. The toy sinks until it rests at the bottom of the pool. The volume of the toy is $2 \times 10^{-5} m^3$.

What is the normal force, in newtons, that the bottom of the pool exerts on the toy? Assume that the density of the pool water is $990 \space kg/m^3$.
