Can Loose Objects in a Car Cause Serious Injury? A Newton's First Law Experiment

AI Thread Summary
The discussion revolves around creating a presentation that illustrates the dangers of loose objects in vehicles, using Newton's first law of motion as a foundation. Participants suggest various demonstration ideas, emphasizing the importance of safety. One participant shares a personal anecdote about a dangerous experience involving heavy tools in a vehicle, highlighting the potential consequences of loose objects during accidents. A safer demonstration is proposed, involving a clear plastic enclosure on a cart containing an egg and a dense object, which effectively showcases the principles of inertia and the risks associated with unsecured items in cars.

Hey there everyone

I need to do a presentation that shows the danger of having loose objects in the car...using Newton's first law...i'm stuck for ideas, we have to make some experiment like an egg on a trolley or something...does anyone have any ideas?

If the loose object is a rattlesnake the demo is pretty easy. :wink:

I once hitched a lift in a lorry carrying over 20 tons of steel bars on a flatbed right behind the cab.
The driver had never heard of Newton's first law. I guess that's why he took the job.
 
My brother-in-law once did just such a demonstration himself. He had a tool-box full of heavy stuff like wrenches, hammers, chisels, etc on the floor of the cab of his pickup and he missed a curve and rolled his truck in the ditch. That toolbox beat the crap out of him. To add to the authenticity, he wasn't wearing his seat-belt (never does!). I'm surprised he's still alive.

You could do a safer demonstration using a clear plastic enclosure on a cart with an egg and a ball-bearing or a large hex nut or some other dense object inside.
 
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...
