16. You are planning to build a solar powered spaceship with mass of 100,000 kg using a reflective solar sail with dimensions of 5km x 5km. Assuming an average solar intensity of 1200 W/m 2 , calculate the maximum radiation pressure exerted on the sails.
17. Unpolarized light of intensity I = 100 W/m2 is transmitted through 3 polarizers with axes oriented as follows: P1 = +x axis, P2 = 30 degrees relative to the +x-axis, and P3 = -45 degrees relative to +x-axis. Calculate the output intensities I1 from the first polarizer, I2 from the second polarizer, and I3 from the third polarizer.
