WebUsing the speed you found, the impulse is: J = Δ p = − ( 80 × 31.3) = − 2504 N ⋅ s. Estimating a duration for the impact with the water of for example 0.3 s, the average force suffered is: F a v e r a g e = J Δ t = − 8348 N. The deacceleration suffered is: a = F a v e r a g e m = − 104 m / s 2. Or 11 g.
