Suppose that you designed a spacecraft to work by photon pressure. The sai l was a completely absorbing fabric of area 1.0 km2 and you directed a red laser beam of wavelength 650 nm on to it from a base on the Moon. What is (a) the force, (b) the pressure exerted by the rad iation on the sa il? (c)Suppose the mass of the spacecraft was 1.0 kg. Given that, after a period of acceleration from standstil l, speed= (force/mass) x time, how long would it take for the craft to accelerate to a speed of 1.0 m s-1?
