AI Thread Summary
As a ball is thrown vertically upward, its velocity decreases until it reaches the peak, where the velocity is zero. After reaching the peak, the ball's velocity becomes negative as it begins to fall back down. The key concept is that gravity continuously acts on the ball, slowing it down as it ascends and accelerating it as it descends. Understanding this motion relies on recalling personal experiences with throwing objects. The problem emphasizes the importance of thinking through the physical principles involved.

Homework Statement


Describe what happens to its velocity as it moves up toward its peak. What is its velocity at its peak? Describe what happens to its velocity after it reaches its peak.

Homework Equations


The Attempt at a Solution


No idea how to solve this.

You actually know what happens because you surely have thrown balls vertically upward. Just close your eyes, remember that memory and describe it. That's all the problem is asking for.
Also, the word "peak", which surely you know what's the meaning of, is actually shouting what velocity the ball has in it.
So all you have to do for answering the question, is starting to think.

Yup, you're right I feel pretty dumb for not getting this at first.
 

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...
