The intensity of the Sun's light in the vicinity of the Earth is about 1000W/m^2. Imagine a spacecraft with a mirrored square sail of dimension 5.5 km. Estimate how much thrust (in newtons) this craft will experience due to collisions with the Sun's photons. [Hint: assume the photons bounce off the sail with no change in the magnitude of their momentum.}

Explanation:

Formula to represent thrust is as follows.

             F =

                =

or,           p =

                  F =

                     =

                     = 201.67 N

Thus, we can conclude that the thrust is 201.67 N.
