Calculate the boy’s average velocity for the time interval from t = 0 to t = 12 s.
A) Velocity is constant, so average velocity is 8 m/s
B) Use the formula v = (s₂ - s₁) / (t₂ - t₁) with s₁ = 0, s₂ = 96 m, t₁ = 0 s, and t₂ = 12 s
C) Average velocity cannot be determined without more information
D) Average velocity is always zero for any time interval
