AI Thread Summary
To avoid a collision, the Magna must reduce its speed from 110 kph to a maximum speed that allows safe stopping distance behind the Commodore, which is traveling at 80 kph. A practical method to determine this speed involves testing various values to gauge stopping distances and reaction times. The discussion emphasizes the importance of calculating safe speeds rather than relying solely on theoretical equations. Participants suggest experimenting with different speeds to find a safe maximum. Ultimately, understanding the dynamics of speed and distance is crucial for collision avoidance.

Homework Statement


Magna is traveling at 110 kph, and realizes Commodore in front of him is traveling at 80kph. To avoid a collision, what is the max speed the Magna can have as it reaches the commodore?

Hi,

One way to approach this is to try a few numbers. Not extremely sophisticated, but it works to get a feeling. 100 ? 50 ?
 

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...
