AI Thread Summary
The car travels a total distance of 4.4 km by completing two laps of a 2.2 km racetrack. The formula for distance is simply the number of laps multiplied by the distance per lap. Displacement for the car is zero since it returns to its starting point after the laps. No specific formula is required to demonstrate this displacement; stating it is sufficient. Clarification from the professor may help resolve any confusion regarding the need for a formula in this context.

The Attempt at a Solution


I know that you have to multiply 2.2km by 2 laps but for my homework i have to show a formula and complete a full answer
(what am i given)
[something] = 2 [meaning laps]
[something] = 2.2 km
\Deltad = ?

(required formula)
\Deltad = [something]*[something]
\Deltad = 2 * 2.2
\Deltad = 4.4 km

(therefore statement)
[therefore] the distance traveled by the runner would be 4.4 km



I know what 2*2.2 is I am not stupid but i don't know the correct formula to use and i don't know what symbols to fill in where the [somethings] are. Help?

Strange question. There is no particular formula other than the distance is equal to the no. of laps multiplied by the distance per lap.

Also if asked for the displacement of the object, it would be 0 due to the circular track you would end where you started correct? Is there a formula for displacement using the given information or what should i show to get 0 as displacement.

You are correct that displacement would be zero but for this problem i don't think you'd have to show anything other than state that its zero.

Mmm alright i'll have to ask my prof on wed. because it wants a forumla..mabey I am supposed to just figure that out or something.
 
There isn't really an equation you can give. You're just using your knowledge that the track starts and ends at the same point.
 
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...
