Question

The California sea lion is capable of making extremely fast, tight turns while swimming underwater. In one study, scientists observed a sea lion making a circular turn with a radius of 0.37 m while swimming at 4.0 m/s.

What is the sea lion’s centripetal acceleration, in units of g?

What percentage is this acceleration of that of an F-15 fighter jet’s maximum centripetal acceleration of 9g?

    Answer:

    Acceleration of Sea Lion is 4.41 g

    This is 49% of maximum jet acceleration given as a = 9g

    Explanation:

    As we know that the radius of the circular loop is given as

    R = 0.37 m

    The speed of the fish is given as

    v = 4 m/s

    Now the centripetal acceleration of the sea lion is given as

    a_c = \frac{v^2}{R}

    a_c = \frac{4^2}{0.37}

    a_c = 43.2 m/s^2

    as we know that

    g = 9.8 m/s^2

    so we have

    a = 4.41 g

    Now Percentage of this acceleration wrt maximum jet acceleration is given as

    P = \frac{4.41 g}{9g} \times 100

    P = 49 %
