    Good Day

    Problem:

    a flower falls from a windowsill 9.2 meters above the sidewalk.

    1. How fast is the flower pot moving when it strikes the ground?

    Given Data:

    a (acceleration) = 9.8 m/s²

    d (distance) = 9.2 m

    Vf (final velocity) = ? unknown

    Vi (initial velocity) = 0 m/s

    Solution:

    We can use the formula Vf = √2ad

    Vf = √2ad

        = √2 × 9.8 m/s²  × 9.2 m

       = √180.32 m²/s²

        = 13.43 m/s

    13.43 m/s

    2. How much time will it take for the flowerpot to hit the ground?

    Given Data:

    a (acceleration) = 9.8 m/s²

    Vf (final velocity) = 13.43 m/s

    Vi (initial velocity) = 0 m/s

    t (time) = ? unknown

    Solution:

    we use the formula t = Vf-Vi/a

    t = Vf-Vi/a

     = (13.43 m/s - 0 m/s)/ 9.8 m/s²

      = 13.43 m/s  / 9.8 m/s²

      =  1.37 seconds

    1.37 seconds

    Dy=(1/2)(g)(t)^2
    dy=(1/2)(9.8m/s^2)(3.41s)^2
    dy=56.97769m
