To find the time taken to change the momentum of a given body, we will use the formula: ΔР = F * t, from where we express: t = ΔР / F.
Variables: ΔР – considered change in momentum (ΔР = 40 kg * m / s); F – acting force (F = 8 N).
Calculation: t = ΔР / F = 40/8 = 5 s.
Answer: The momentum of a given body has changed by 40 kg * m / s in 5 seconds.
