    Drop Velocity
AI Thread Summary
To determine the drop required for a 225 lbs object to achieve a velocity of 10 fps at the lowest point, the problem involves using equations of motion related to acceleration and distance. The discussion highlights the need for clarity on whether the object starts from rest or has an initial speed. It suggests using formulas that relate final velocity, acceleration, and distance, emphasizing the importance of consistent units, either metric or imperial. Participants are encouraged to calculate the necessary drop by applying these principles. The conversation aims to guide towards a solution using basic physics concepts.

Welcome to PF!
The question isn't entirely clear to me - is it just an object dropping distance d from initial speed zero and final speed 10 ft/s?
If so, you need an accelerated motion formula relating Vf, a, and d. If you can't find one like that, you can use the two basic accelerated motion formulas for v and d to find the time and then the distance. Also, you must either convert everything to metric units and use a = 9.81 m/s² or else find the US value for the acceleration of gravity. Try putting that together and show us how far you get!
 

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 '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...
