Calculate the Overall Velocity of Dropped Hamper from 3000m Height

[snowbelle]

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 don't get the problem, do I have to find the x component first? then what do I do after?

Yes, you can use this to find the downward component of velocity:

v² = u² + 2as

Where v = final velocity
u = initial velocity
a = acceleration &
s = displacement

Then use pythagoras for the magnitude of velocity

Remember that the horizontal velocity (x-component) always stays the same if there is no friction in that direction (like in this problem)

Oh yeah, I forgot; my answer assumes that there is no air-resistance.

Cheers for the reminder daniel_i_l.
