Sharks are generally negatively buoyant; the upward buoyant force is less than the weight force. This is one reason sharks tend to swim continuously; water moving past their fins causes a lift force that keeps sharks from sinking. A 92 kgbull shark has a density of 1040 kg/m3. What lift force must the shark's fins provide if the shark is swimming in seawater? Bull sharks often swim into freshwater rivers. What lift force is required in a river?

    866.92 N

    Explanation:

    mass of shark, m = 92 kg

    density, d = 1040 kg/m^3

    Volume, V = mass / density

    V = 92 / 1040 = 0.08846 kg/m^3

    The lift force is the buoyant force acting on the shark is

    Lift force = Volume x density of water x g

    Lift force = 0.08846 x 1000 x 9.8

    Lift force = 866.92 N

    Thus, the lift force is 866.92 N.
