A plane drops a hamper of medical supplies from a height of 2560 m during a practice run over the ocean. The plane’s horizontal velocity was 116 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
