AI Thread Summary

To calculate the coefficient of friction for a bike starting from rest and covering 1 km in 100 seconds, the equation s = (1/2)at^2 is used, where s is the distance, a is acceleration, and t is time. The bike's acceleration can be determined by rearranging the equation to find a, resulting in a value of 0.02 m/s². The force of friction, which is responsible for the bike's acceleration, can be expressed as F_friction = m*a, where m is the mass of the bike and rider. The coefficient of friction (μ) can then be calculated using the formula μ = F_friction / F_normal, where F_normal is the normal force. This analysis highlights the relationship between distance, time, acceleration, and friction in determining the coefficient of friction for the bike.

A bike starts from rest. It covers a distance of 1km from rest to rest. If the minimum time in which the bike covers the distance is 100s, the coefficient of friction between road and tyre = ?

s = (1/2)at^2

no idea how to go about it.

Remember the force with which the bike accelerates is friction's.

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:
