Momentum and Its ConservationProblem of the Week (1.0K) | (0.0K) | (0.0K) | Solve
the impulse-momentum equation for time: | | (1.0K) | | The
craft will not actually need all this time to achieve 22 000 mph
because it will have an initial velocity due to Earth's orbital
speed around the sun. This initial velocity will be on the order
of thousands of miles per hour. | | (0.0K) | To
determine mass of xenon atoms expelled per second, that is,
expelled in one second, use the impulse-momentum equation and
solve for mass. | | (1.0K) | | Calculate
the number of xenon ions, N, by using the mass number
of xenon, Z = 131 g/mol and the Avogadro constant,
NA | | (1.0K) | | 8.2 x 1018
xenon ions per second are expelled from the engine. | | (0.0K) | (0.0K) | (0.0K) | (0.0K) | (0.0K) |
