The molecules of a five-particle gas have these velocities: 3.0i + 4.0j, - 2.0i + j, - 5.0j, i - 2.0j, and -2.0i + 2.0j. The average velocity of the gas is

Question

Quizplus · Accepted Answer

To find the average velocity of the gas, sum the components of the velocities and divide by the number of particles. For the i component: (3.0 - 2.0 + 0 + 1.0 - 2.0)/5 = 0. For the j component: (4.0 + 1.0 - 5.0 - 2.0 + 2.0)/5 = 0. Therefore, the average velocity is 0.0 m/s.
