bigger acceleration......................
Answer:
The displacement, s= 0 m
Explanation:
Given data,
The average velocity of the duck, v = 0 m/s
The time interval of the velocity, t₁ = 0 and t₂ = 120 s,
∴ Δt = t₂ - t₁
= 120 s
The displacement of the duck is given by the formula,
s = v x Δt
= 0 m/s x 120 s
= 0 m
Hence, the displacement of the duck is, s = 0 m
The correct option is b i.e none is correct.
The instantaneous velocity would be zero at the top but the acceleration would not be zero at that point. This is because the acceleration is the rate of change of velocity. since, the velocity is not constant, hence the acceleration would not be zero. The correct answer would be option b: None is correct.
