The average value of the squared 2 speed does not equal the square of the average
Question:
The average value of the squared ῡ2speed does not equal the square of the average speed (ῡ)2 To verify this fact, consider three particles with the following speeds: v1 = 3.0 m /s, v2 = 7.0 m/s, and v3 = 9.0 m/s. Calculate
(a) ῡ2 = ⅓ (v12 + v22 + v32 ) and
(b) (ῡ)2 = [ ⅓ (v1 + v2 + v3 )]2
