Fifteen identical particles have various speeds: one has a speed of 2.00 m/s, two have speeds of 3.00 m/s, three have speeds of 5.00 m/s, four have speeds of 8.00 m/s, three have speeds of 9.00 m/s, and two have speeds of 14.0 m/s. (a) Find the average speed (in m/s). m/s (b) Find the rms speed (in m/s). m/s (c) Find the most probable speed of these particles (in m/s). m/s (d) What If? How many additional particles with a speed of 14.0 m/s must be added to the original fifteen particles for the average speed to become 10.0 m/s ? (Round your answer to at least the nearest integer.) particles (e) What would be the rms speed of the original plus additional particles (in m/s)? m/s
