Consider a number of particles with different speeds. There are 10 particles and they are all identical: two have a speed of 27 m/s; four have speeds of 33 m/s; two have speeds of 40 m/s; and two have speeds of 57 m/s. What is the rms speed? O a. 39 m/s O b. 6.2 m/s O c. 1300 m/s O d. 1600 m/s O e. 37 m/s
