A force `vecF=vecvxxvecA` is exerted on a particle in addition to the force of gravity, where `vecv` is the veocity of the particle and `vecA` is a constant vector in the horizontal direction. With what minimum speed a particle of mass m be projected so that it continues to move undeflected with a constant velocity?
