A jet comes in for a landing on solid ground

AI Thread Summary
A jet landing at a speed of 100 m/s can decelerate at a maximum of 5.00 m/s². To determine the minimum time required for the jet to come to rest, calculations indicate it would take 20 seconds. The runway length of 0.800 km is sufficient for the jet to stop, as the stopping distance calculated is less than the available runway. The equation v² = 2as confirms that the jet can safely land and stop within the given distance. Thus, the jet can land at the small tropical island airport.

Homework Statement


A jet comes in for a landing on solid ground with a speed of 100m/s, and its
acceleration can have a maximum magnitude of ##5.00m/s^2 ## as it comes to rest.

(a) From the instant the jet touches the runway, what is the minimum time
interval needed before it can come to rest?
(b) Can this jet land at a small tropical island airport where the runway is 0.800Km long?
(c) Explain your answer.

Yes. You could also use ##v^2 = 2as##.

Although, I guess you still have to explain what the ##1km## you got represents.
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
