AI Thread Summary

A .565 kg football is kicked at a speed of 22 m/s and the discussion focuses on determining its speed as it passes 5 meters high. Participants suggest using conservation of energy principles instead of kinematics equations to solve the problem. The key factors include the initial speed and height of the football. The conversation emphasizes the importance of understanding energy conservation in projectile motion. The final speed of the football at that height is the main goal of the discussion.

help! its driving me nuts!

a .565kg football is kicked from the ground at a speed of 22 m/s. what is its speed just as it passes between the uprights 5.0 m above the ground?

please help!

G:
m= .565 kg
v= 22m/s
5.0 m

r:
velocity

a:no kinematics's equations

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
