AI Thread Summary
A car traveling at 32 m/s flips over and skids on the road, with a friction coefficient of 0.42. The initial and final velocities are 32 m/s and 0 m/s, respectively. The problem initially seemed unsolvable without mass, but it can be addressed by calculating acceleration using the friction force equation. The correct approach involves using the coefficient of friction multiplied by gravitational acceleration to find the deceleration. Ultimately, the mass of the car is necessary for a complete solution, highlighting a flaw in the problem's setup.

Homework Statement


A car traveling at 32 m/s flips over onto its roof and skids down the road. If the coefficient of friction between metal and the pavement is 0.42, calculate how far the car will travel before coming to a complete stop.


Homework Equations


F=ma, Force of Kinetic Friction= Coefficient of Friction x Normal Force


The Attempt at a Solution


The car's initial velocity is 32m/s and its final velocity is 0m/s. Thus V0 is 32m/s and V1 is 0m/s. Given mass, acceleration, or time the problem would be simple. But given only velocity and the coefficient of friction I'm not even sure if this problem is possible.

Help?

EDIT: Solved.

It is possible. Try using the equation for the force of friction to solve for the acceleration and watch the magic happen.
 
My god, how did I miss that?

So that leaves me with the equation acceleration=coefficient of friction x acceleration due to gravity.

Thanks a ton!
 
You need the mass of the car. tell whoever gave you that problem to clean up their act.

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'

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...
