AI Thread Summary
When two identical balls are dropped from rest at different times, the distance between them initially increases but eventually remains constant after the second ball is dropped. The first ball accelerates due to gravity, while the second ball, dropped later, starts from rest and accelerates as well. The general equations for position and velocity under constant acceleration are essential for understanding their motion. The distance between the balls can be calculated using the formula for free fall, which considers gravitational acceleration. Familiarity with these equations is crucial for solving related physics problems.

1. Two identical balls are dropped from rest, one at t=0, and the other a second later. Does the distance between them increase, decrease or remain the same.? Explain.

2. Write the general equations, in one dimension, for position and velocity of an object which experiences a constant acceleration.

Someone please help..i have no idea how to answer this. Thanks

Do you know how to do #2?

For #1, just think about it. In between t=0 and t=1, will the balls be getting farther apart? After t=1, will the balls have identical velocity?
 
no they will not have identical velocities. so yea they will be the same distance between them. I don't know 2,

Are you sure? What is the formula for distance of free fall in a gravity field? At the 3 second mark how far are they apart. At the 5 second mark how far apart are they?
 
i don't know wat formula ur tokin abt
 

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...
