Question: The average value of the squared 2 speed does not equal the square of the average speed () 2 To verify this fact, consider

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
