AI Thread Summary
To determine how far a car skids before stopping after slamming on the brakes, one must apply Newton's Laws and the principles of friction. The car's initial velocity is 20 m/s, and its mass is 1200 kg, with coefficients of friction of 0.4 and 0.6. By calculating the deceleration using the frictional force, the stopping distance can be derived from the relationship between acceleration, initial velocity, and time. The equations ΣF=Δp/Δt and v=u-at are essential for finding the necessary values. Understanding these relationships will lead to the solution of the skidding distance.

Homework Statement


While driving your car at 20 m/s (about 45 mph) along a country road one night, you suddenly see a deer in your headlights. Your car's mass is 1200 kg, and the coefficients of friction between its tires and the asphalt road are 0.4 and 0.6.
If you slam on your brakes and lock the wheels, how far will you skid before stopping if the road is level?
I have no idea on how or where to start.

Take a second and step back, then write down what each number of information represents. then see what equations use the information. Then make an attempt to solve

Certainly you know something.

Newton's Laws, friction, acceleration, velocity, time ...

How are they related?
 
Try using ΣF=Δp/Δt. You should find Δt from this equation. Then you use this one to find the acceleration: v=u-at. Can you find out what comes next?

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...
