A rubber duck of volume 2,500cm3 floats in water with 20% of its volume submerged. You want to hold the duck under water so it is at rest and completely submerged. How much force do you have to apply? If you release the duck, what will be its acceleration at that instant?

The force applied to the submerged rubber duck is 4.9 N.

Density of the rubber duck

The density of the rubber duck is calculated as follows;

ρ = S.G x density of water

ρ = 0.2 x 1000 kg/m³

ρ = 200 kg/m³

Force applied to the duck

F = mg = (ρV)g

F = (200 x 0.0025) x 9.8

F = 4.9 N
