a plane drops a hamper of medical supplies from a height of 3000m. the plane`s horizontal velocity was 105m/s at the instant the hamper was dropped. acceleration of gravity is 9.8 m/s what is the overall velocity of the hamper at the instant it strikes the surface of the ocean? answer in units of m/s I dont get the problem, do I have to find the x component first? then what do I do after?
