A small spaceship whose mass is 2000 kg (including an astronaut) is drifting in outer space with negligible gravitational forces acting on it. If the astronaut turns on a 12 kW laser beam, what speed will the ship attain in 6.0 days because of the momentum carried away by the beam? Number Units

Some scientists have suggested that spacecraft with sails of the kind described in Conceptual Example 4 could be propelled by lasers. Suppose such a sail is constructed of a highly reflective material thin enough so that one square meter of the sail has a mass of just 5.3×10−3 kg. The sail is to be propelled by an ultraviolet laser beam (wavelength = 215 nm) that will strike its surface perpendicularly. (a) Use the impulse-momentum theorem to determine the number of photons per second that must strike each square meter of the sail in order to cause an acceleration of 9.8×10−6 m/s2, which is one million times smaller than the gravitational acceleration at earth's surface. Assume that no other forces act on the sail, and that all the incident photons are reflected. (b) Determine the intensity (power per unit area) that the laser beam must have when it strikes the sail. (a) Number Units (b) Number Units

Review Conceptual Example 5 as background for this problem. Suppose some nucleus undergoes α decay, releasing 5.7 MeV of energy. If the daughter product of this reaction is 92 236 X (atomic mass = 236.04556), it will recoil away as the α particle leaves. Determine (a) the energy of the daughter product and (b) the energy of the α particle (atomic mass = 4.002603 u). Assume that the energy of each particle is kinetic energy, and ignore any other small amounts of energy that might be carried away by other emissions. In addition, ignore relativistic effects. Before decay α particle After decay (a) Number Units (b) Number Units
