Freefall Acceleration of a Raindrop

AI Thread Summary
A raindrop falling from 1700 meters accelerates at 9.81 m/s², resulting in a calculated impact velocity of 182.63 m/s without considering air resistance. This velocity seems excessively high, indicating that air resistance plays a significant role in the actual fall of a raindrop. The calculations were confirmed to be correct, alleviating concerns about potential errors. Stokes' resistance law provides a more realistic estimate of fall velocity for small spheres like raindrops. Ultimately, neglecting air resistance leads to unrealistic results in freefall scenarios.

I have an answer that does not seem right:

The raindrop falls from 1700m high with constant acceleration of 9.81 m / s^2
What is the velocity of the raindrop not considering any resistance?

i used y - yo = vo * t - (1/2) g t^2 to get the time to hit the ground at 18.62 seconds.

I then plugged that into v = vo + a t to get 182.63 m / s which seems kind of fast for a raindrop, right? Can anyone help? Please?

So that would imply, that in reality, you cannot ignore air resistance, if you want a meaningful value for the velocity of a rain drop. I did not check your numbers but they do not seem unreasonable, for this ideal but unrealistic scenario.

Edit, checked your numbers they are right in all of the signifiant digits.

Thank you for the help :approve: I always get worried that I did something wrong when numbers do not turn out to appear reasonable.
 
Check out Stokes' resistance law on a sphere moving through a viscous fluid.
This yields a fall velocity consistent with experiments on the fall velocity of fog droplets.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
