An airplane is moving horizontally with a constant velocity of (+ 115 m/s) at altitude of 1050 m. the directions to the right and upward have been chosen as the positive directions. the plane releases a "care package' that falls to the ground along a curved trajectory. ignoring air resistance, determine the time required for the package to hit the ground

The time required for the package to hit the ground = 14.63 seconds.

Explanation:

Considering vertical motion of care package:-

Initial velocity, u =  0 m/s

Acceleration , a = 9.81 m/s²

Displacement, s = 1050 m

We have equation of motion s= ut + 0.5 at²

Substituting

   s= ut + 0.5 at²

    1050 = 0 x t + 0.5 x 9.81 x t²

    t = 14.63 seconds

The time required for the package to hit the ground = 14.63 seconds.
