AI Thread Summary
When a car collides with a wall, it experiences a sudden deceleration, causing it to stop abruptly. The object on the passenger seat, due to inertia, will continue moving forward at the car's previous speed until acted upon by another force. This force could be the seatbelt, the dashboard, or the airbag, which will eventually stop the object. The discussion emphasizes the concepts of inertia and the forces acting on the object during the collision. Understanding these forces is crucial for analyzing the motion of objects in a vehicle during an impact.

1. The problem statement
An object is sitting on the passenger seat of a car. The car is moving and it collides with a wall. Explain using forces, how the object moves after the car hits the wall?

Well, the car will stop, so what will happen to the object?

And what are the forces on the object?
 
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...
