Friction Kinetic Kinetic friction

AI Thread Summary

To determine the coefficient of kinetic friction for a sliding car, first calculate the car's acceleration using the formula for motion, where initial velocity is 98 km/hr and the stopping distance is 91 m. Convert the speed to meters per second for accurate calculations. Using the equation of motion, find the deceleration caused by friction. Finally, apply the formula for the coefficient of kinetic friction, which is the ratio of the frictional force to the normal force, to solve for the coefficient. This approach provides a clear method to find the coefficient of kinetic friction in this scenario.

Hint: First solve for the acceleration.

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:
