Calculating Maximum Speed of a Swinging Girl

AI Thread Summary
The discussion focuses on calculating the maximum speed of a girl swinging on a swing with a length of 4.00m, reaching a maximum height of 2.00m above the ground. The key concept involved is the conservation of energy, which relates potential energy at the highest point to kinetic energy at the lowest point. The calculated maximum speed is 5.42m/s. There is a reminder for users to post homework questions in designated forums. The conversation emphasizes understanding energy conservation principles for solving similar problems.

A girl swings back and forth on a swing with ropes that are 4.00m long. The maximum height she reaches is 2.00m above the ground. At the lowest poing of the swing, she is 0.500m above the ground. What is the girl's maximum speed?

The answer is 5.42m/s, I just need to know how to do the problem.

Welcome to the forums,

Have you met the concepts of conservation of energy?

P.S. Homework questions should be posted in the homework forums
 
Whoops, I just got on the fourms like 5 minutes ago, I didnt know there was a separate HW fourm, I will repost this there.
 

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...
