Finding mass with acceleration and velocity

AI Thread Summary
To find the mass of the raindrop, apply Newton's second law, where the sum of forces equals mass times acceleration (F = ma). The force of air resistance is given as 5.3x10^-5 N, which balances the gravitational force at terminal velocity. Using the acceleration due to gravity (9.8 m/s²), the net force acting on the raindrop is zero at terminal velocity. Therefore, the mass can be calculated by rearranging the equation to m = F/g, resulting in a mass of approximately 0.0054 kg. This calculation demonstrates the relationship between force, mass, and acceleration in the context of terminal velocity.

Homework Statement



the force of air resistance on a raindrop is 5.3x10-5N when it falls with a erminal velocity of 5.3 m/s.

the acceleration of gravity is 9.8 m/s2.

what is the MASS in Kg of the raindrop?

Write that the sum of the forces = ma.
 
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...
