AI Thread Summary

In a collision between a truck and a car, the change in velocity will not be the same due to their differing masses. While momentum is conserved, the formula p=mv indicates that the change in momentum will be equal for both vehicles. This means that the truck, having a larger mass, will experience a smaller change in velocity compared to the car. Therefore, the relationship between mass and velocity change is crucial in understanding the dynamics of the collision. The discussion highlights the importance of mass in determining the effects of momentum in collisions.

If a truck and a car collide will they both have the same change in velocity?

Since the momentum before has to equal the momentum afterward wouldn't the change in the velocity also be equal?

Thank you.

No, because they have different masses. Their change in momentum will be equal, p=mv.

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:
