AI Thread Summary
To calculate the velocity of a 1.0g raindrop falling from a height of 1.0km while ignoring friction, start with the gravitational force equation Fg = mg, yielding Fg = 0.00981 N. The problem hints at using the relationship between initial and final velocity, as well as acceleration, assuming the raindrop starts from rest. The acceleration due to gravity is a constant 9.81 m/s². By applying kinematic equations, the final velocity can be determined based on the height fallen and the known acceleration. This approach will yield the raindrop's terminal velocity upon reaching the ground.

Homework Statement


Calculate the velocity a 1.0g raindrop would reach if it fell from a height of 1.0km. You may ignore all forces of friction.

Homework Equations


Fg = mg, where g = 9.81 m/s^2
W = Fparallel x d


The Attempt at a Solution


I used Fg = mg to find that Fg = 0.00981 N.
Then, I had no clue what formula to use after this :S.

Thanks.

There's a connection between:

you're starting and ending velocity
and
your acceleration

hint: assume the drop starts from rest... so you know the starting velocity. And the acceleration is also a known constant.

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...
