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?

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
