Answer #1

If the speed of Penguin is constant, then

Thrust force = Drag force = 0.0044 (unit will be same as in question e.g. Newton)

NOTE: The question does not specify unit of drag and it not very clear whether it is talking about Drag force or Drag co-efficient; Please refer above answer if it is Drag force. If we have drag co-efficient (Cd) and value of u then we can calculate drag force as:

Fd = (1/2) * ρ * u2 * Cd * A

where, ρ = Density of fluid (SI unit = kg /m3)

u = Flow speed (SI unit = m/s)

A = area (SI unit = m2)

Cd = Drag co-efficient (unitless)
