The radiation pressure at earth’s surface is 6 mpa. consider a space ship with a surface area of 100 100 m2 and mass of 104 kg. if released with an initial velocity of 0, what is the speed with which the ship could reach the orbit of mars? assume the pressure does not change. also ignore angular momentum. the radius of earth’s orbit is 1.5 1011m while mars’ orbit radius is 2.3 1011 m.
