When gas expands in a cylinder with radius r, the pressure P at any given time is a function of the volume V: P = P(V). The force exerted by the gas on the piston (see the figure) is the product of the pressure and the area: F = ner2p. The work done by the gas when the volume expands...

Problem 34.56 Part A You've recently read about a chemical laser that generates a 20.0-cm- What speed would such a block have if pushed horizontally 96.0 m along a frictionless track by such a laser? Express your answer with the appropriate units. diameter, 22.0 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,...
