    Answer:

    the orbital speed of umbriel is 16,800 km/h

    Explanation:

    The computation of the orbital speed is shown below

    According to the question the Data provided in the question

    Uranus mass = 8.68 × 10^25 kg

    Distance = 2.66 × 10^8 m

    Based on the above information, the orbital speed of Umbriel is

    V = \sqrt{\frac{GM}{R} } \\\\ = \sqrt{\frac{((6.673e-11)(8.68e25)}{2.66e8} }

    V = 4666 m/s

    = 16,800 km/h

    Hence, the orbital speed of umbriel is 16,800 km/h

    Therefore it can be calculated by applying the above formula
