A plane drops a hamper of medical supplies

Question

from a height of 5750 m during a practice run
over the ocean. The plane’s horizontal velocity was 109 m/s at the instant the hamper
was dropped.
What is the magnitude of the overall velocity of the hamper at the instant it strikes
the surface of the ocean? The acceleration of
gravity is 9.8 m/s
2
.
Answer in units of m/s

Answer 1

V^2 = Vo^2 + 2g*h.
V^2 = 0 + 19.6*5750 = 1127000
V = 1062 m/s.
