Calculating Initial Speed - Revisited

AI Thread Summary
The discussion revolves around calculating the initial speed of an egg thrown vertically upward, which is determined to be 14.5 m/s. The problem states that the egg reaches a point 50.0 m below its starting position after 5.00 seconds, with air resistance ignored. Participants seek clarification on the calculations leading to this initial speed and additional questions regarding the egg's maximum height and velocity at that height. The original poster acknowledges a mistake in their algebra, which contributed to their confusion. The focus remains on understanding the physics concepts and calculations involved in the problem.

I found the exact question I'm trying figure out here:

https://www.physicsforums.com/showthread.php?t=91948

My exercises are all online and I can view the correct answer if I choose to (or if I answer incorrectly 5 times). Well, now I know the correct answer is 14.5 m/s. I still don't understand how they end up with this. Any clarification would be great! Dumb it down for me!

Here is the problem:

An egg is thrown nearly vertically upward from a point near the cornice of a tall building. It just misses the cornice on the way down and passes a point a distance 50.0 m below its starting point at a time 5.00 s after it leaves the thrower's hand. Air resistance may be ignored.

What is the initial speed of the egg? apparently 14.5 m/s

It also asks:

How high does it rise above its starting point?

What is the magnitude of its velocity at the highest point?

What is the magnitude of its acceleration at the highest point?

Sorry, I found what I was doing wrong. Screwed up the algebra :blushing:
 

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...
