AI Thread Summary
Four-wheel brake pads can improve stopping distance compared to front-wheel-only brake pads in cars, as they distribute braking force more evenly across all wheels. This enhanced braking capability can lead to better control and stability during stops. However, the effectiveness may vary depending on the vehicle type and conditions, such as weight distribution and road surface. In contrast, sportbikes may not experience the same benefits on dry pavement due to their design and weight dynamics. Overall, using brake pads on all four wheels generally contributes to shorter stopping distances in cars.

Would a car with break pads on all four wheels stop in a shorter distance than a car with break pads on just the front wheels? please explain.

Sure. But that's not true of a sportbike on dry pavement. Why not?

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...
