We assume that Bt is a closed ball in the half-space x3>0 in R3, striking the wall (= the x1, x2–plane) at time tc in (0, T ). The speed of the ball at the instant of the collision need not be zero. Although a weak solution to the Navier-Stokes equation with Dirichlet’s no-slip boundary condition does not exist if the speed of the stroke is non-zero, we prove that such a solution may exist if Dirichlet’s boundary condition is replaced by Navier’s slip boundary condition.
