Car Centripetal Centripetal force Force Racing

AI Thread Summary

To calculate the centripetal force acting on a racing car traveling on a circular course, first determine the speed using the formula for circular distance, which is 2πr. Given the radius of 641 meters and a speed of 1.7 revolutions per minute, the velocity can be calculated. The centripetal acceleration is then found using the formula a = V²/r. Finally, the centripetal force is calculated using CF = ma, where m is the mass of the car at 1990 kg. The problem was successfully resolved by applying these principles.

a racing car is traveling on a circular course of radius 641m at a speed such that it makes 1.7 rev in 1 minute. THe mass of the car is 1990kg. what is the centripetal force acting on the car?

CF=ma=mass*acceleration
a=V^2/r

how do you find v?

you use the fact that its traveling in a circle (distance = 2*pi*r), time can be found from the number of revs per minute.

thank you i figured it out

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:
