    Set Swing
AI Thread Summary
Setting a swing in motion with an initial velocity of 33 ft/s for a child weighing 66 pounds is deemed nearly impossible due to the extreme acceleration required. The discussion suggests that if the child were stationary on a surface like ice, achieving such a speed would still be unfeasible, as it exceeds typical human running capabilities. Calculating the necessary acceleration to reach this velocity from rest reveals the impracticality of the scenario. Additionally, the implications of a collision with another child at that speed raise further concerns about safety and feasibility. Overall, the consensus is that achieving this speed on a swing is not realistic.

Is it impossible for me to to set a swing (on which a child weighing 66 pound is sitting) going, so that its velocity from the very beginning is 33 ft/s? Why/Why not?

I find myself quite lost with this question so I have no attempts at any solutions...all i know is that it sounds impossible to me..but i don't know how to prove it:S Maybe one could in some way use momentum p=m*v ...

Would really appreciate some help!:)

Well, suppose the child, instead of being stationary on a swing, was stationary on the ground (say, on ice) …

could you then set the child moving at 33 ft/s ?
 
No probably not...i mean it's almost impossible to even run that fast..
But aren't there any equations i can use to prove it??
 
Well, try calculating the acceleration that would be needed to set anyone moving with any velocity in no time assuming that the velocity in the beginning was 0 :P. This advice is not as stupid as it seems to be ;)

What would happen if another child collided with it?
 

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'

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...
