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.
