Aplane drops a hamper of medical supplies from a height of 2830 m during a practice run over the ocean. the plane’s horizontal velocity was 106 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.

Overall velocity will be 258.27 m/sec  

Explanation:

We have given height = 2830 m

Acceleration due to gravity

Horizontal velocity

From third equation of motion

As the hamper is drooped so u=0

Overall velocity is given by

So overall velocity will be 258.27 m/sec

ok

explanation:

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
