You've recently read about a chemical laser that generates a 20-cm-diameter, 25.0 mw laser beam. one day, after physics class, you start to wonder if you could use the radiation pressure from this laser beam to launch small payloads into orbit. to see if this might be feasible, you do a quick calculation of the acceleration of a 20-cm-diameter,
100 kg, perfectly absorbing block. what speed would such a block have if pushed horizontally 100 m along a frictionless track by such a laser?

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
