How Is Work Done by Air Resistance Calculated in a Falling Raindrop Scenario?

AI Thread Summary
In a scenario where a 0.459 kg raindrop falls at a constant speed, the work done by gravity is calculated to be 634.246 J after falling 141 m. To determine the work done by air resistance, the work-energy theorem can be applied, which states that the total work done equals the change in kinetic energy. Since the raindrop falls at a constant speed, its kinetic energy remains unchanged, indicating that the work done by air resistance must equal the work done by gravity but in the opposite direction. Therefore, the work done by air resistance is also 634.246 J. This analysis highlights the balance between gravitational force and air resistance in a falling object scenario.

Homework Statement



a .459kg raindrop falls vertically at constant speed under the influence of gravity and air resistance. acceleration due to gravity is 9.8 m/s

after the drop 141 m, the work done by gravity is 634.246 J

a problem ask the work donde by air resistance
the work done by gravity is 634.246J

Homework Equations



i just know regular force and work

w=f*change in x/y
f= m*g

The Attempt at a Solution



i don't know what to do

Hi PepeF.! :smile:

Hint: use the work-energy theorem …

total work done = change in kinetic energy :wink:​
 

Thread 'Errors and significant figures'

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

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...
