Integrated Concepts Sunlight above the Earth's atmosphere has an intensity of 1.30kW/m 2 . If this is reflected straight back from a mirror that has only a small recoil, the light's momentum is exactly reversed, giving the mirror twice the incident momentum. (a) Calculate the force per square meter of mirror. (b) Very low mass mirrors can be constructed in the near weightlessness of space, and attached to a spaceship to sail it. Once done, the average mass per square meter of the spaceship is 0.100 kg. Find the acceleration of the spaceship if all other forces are balanced. (c) How fast is it moving 24 hours later?

Although it is not possible, imagine a scenario where we could take the entire mass of a 1.1 kg wrench and covert it completely in to energy. How many MJ would this be? MJ
Sunlight above the Earth's atmosphere has an intensity of 1.39 kW/m2. If this is reflected straight back from a mirror that has only a small recoil, the light's momentum is exactly reversed, giving the mirror twice the incident momentum. Calculate the force per square meter of mirror (in N/m2).
b) Very low mass mirrors can be constructed in the near weightlessness of space, and attached to a spaceship to sail it. Once done, the average mass per square meter of the spaceship is 0.162 kg. Find the acceleration (in m/s2) of the spaceship if all other forces are balanced.
c) How fast (in m/s) is it moving 24 hours later? (Assume the spaceship started from rest.)
