Intro Physics Question: Avoiding Collision on NY State Thruway at 106.8 km/hr

AI Thread Summary
To avoid a collision on the New York State Thruway while traveling at 106.8 km/hr, it's crucial to calculate the safe distance behind the car in front when it brakes. Given a 1-second reaction time before applying brakes, the stopping distance must account for both the initial speed and the maximum deceleration. Using standard physics equations, one can determine the necessary distance to maintain safety. The discussion highlights the importance of understanding acceleration and deceleration in driving scenarios. Proper calculations can prevent accidents in high-speed traffic situations.

You are driving along the New York State Thruway in
a line of cars all traveling at a constant speed of 106.8 km/hr.
The car in front of you applies its brakes for maximum accelera-
tion. You then apply your brakes to achieve the same maximum
acceleration after only a 1 s delay due to reaction time. What
distance behind the car in front of you must you be to avoid a
collision?

When I want to make MY car accelerate, I hit the gas. I find it very weird that you hit the brakes to accelerate.
 

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'

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...
