    Answer:

    the horizontal distance is 4.355 meters

    Explanation:

    The computation of the horizontal distance while travelling in the air is shown below:

    Data provided in the question is as follows

    Velocity = u = 7.70 m/s

    H = 1.60 m

    R = horizontal direction

    Based on the above information

    As we know that

    R = u × time

    where,

    Time = \sqrt{\frac{2H}{g} }

    So,

    = 7.70\times \sqrt{\frac{2\times 1.60}{10} }

    = 4.355 meters

    hence, the horizontal distance is 4.355 meters
