Question

A plane drops a package for delivery. The plane is flying horizontally at a speed of 120m/s,and the package travels 255 m horizontally during the drop. We can ignore air resistance.What is the package’s vertical displacement during the drop?

    Answer:

    Package’s vertical displacement(s) = 22.12 meter

    Explanation:

    Given:

    Speed of plane = 120 m/s

    Total distance = 255 m

    Find:

    Package’s vertical displacement(s)

    Computation:

    Time taken = Distance / Speed

    Time taken = Total distance / Speed of plane

    Time taken = 255 / 120

    Time taken = 2.125 s

    Acceleration due to gravity(g) = 9.8 m/s²

    Initial velocity (u) = 0

    So,

    Package’s vertical displacement(s) = ut + (1/2)gt²

    Package’s vertical displacement(s) = (0)(2.125) + (1/2)(9.8)(2.125)²

    Package’s vertical displacement(s) = 22.12 meter
