Earth’s orbit Physics problem?

[BunnyL_08]

Near the Earth’s orbit, the sunlight delivers approximately 1400 W/m^2 at normal incidence. One proposed form of space propulsion is the “solar sail”, driven by light pressure. What is the pressure due to sunlight at normal incidence on a perfectly
reflecting sail? What is the force due to this pressure acting on a sail of area of 25 m^2? If such a sail is very thin, and has a mass of only 10 g, what would be the Sun’s gravitational force on the sail? (The radius of Earth’s orbit around the Sun is 1.5x10^11 m.) If released from rest, what will be the speed of that sail after one day? (Ignore Earth’s gravitation, the friction of Earth’s atmosphere, and assume that the forces on the sail stay constant for that day)
