AI Thread Summary
To calculate the overall velocity of a hamper dropped from a height of 3000m, the horizontal velocity of 105 m/s remains constant due to the absence of friction. The downward component of velocity can be determined using the equation v² = u² + 2as, where the initial vertical velocity is zero, acceleration is 9.8 m/s², and displacement is 3000m. After calculating the vertical velocity, the overall velocity can be found using the Pythagorean theorem to combine both horizontal and vertical components. The discussion emphasizes that air resistance is not considered in this scenario. The final calculation will yield the overall velocity in m/s at the moment the hamper strikes the ocean.

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.

thanks so much guys

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
