AI Thread Summary
To determine the smallest mass needed to move a 63.5 kg object, the average force required to initiate movement must be calculated. Key variables include the force needed, the duration of contact, and the velocity of the moving mass. The relevant equations, such as F = ma and momentum equations, are acknowledged but not yet applied. The discussion highlights the challenge of proceeding without additional information or context for the experiment. Understanding these principles is essential for developing a hypothesis and successfully conducting the experiment.

Homework Statement


What is the smallest possible mass needed to move a 63.5 kg mass? To find this, I need to know the force need to move the known mass, time the unknown mass stays in contact with the known mass, and velocity at which the unknown mass is traveling. I believe I can find out the rest of this information if I know the average force required to move a 63.5 kg mass.


Homework Equations


F = ma, I = Fav\Deltat = \Deltap, p = mv


The Attempt at a Solution


What I have done so far...nothing really. I need this information to move forward, and I don't know of a way to calculate it with the information available.

Whats the rest of the question?
From what you have you can't really get anywhere
 
I'm not sure if there is a rest of the question. We were just assigned to perform an experiment. We decided on seeing how little a mass we need to move a person who is 63.5 kg and I've been trying to use physics to develop a supported hypothesis before we started. That is all the information I could think of.
 

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...
