A special black material absorbs all light incident upon it. An intense laser beam shines straight up onto a horizontally flat object made out of this material. If the object has an area of 1.0 m² and a mass of 1.0 kg, how much power does the laser need to generate in order to accelerate it upward at a rate that is two times the freefall acceleration of gravity, 2g?
