You have recently read about a chemical laser which produces a 20 cm-diameter, 21.0 MW laser beam. One day, after physics class, you begin to wonder whrn you could use the radiation pressure from this laser beam to launch small payloads into orbit. To see when this might be feasible, you do a quick computation of the acceleration of a 20 cm diameter, 93.0 kg, and perfectly absorbing block.
Determine what speed would such a block have when pushed horizontally 101 m all along a frictionless track by such a laser?
