Once it hits the runway, how long till the Jet stops?

AI Thread Summary
To determine how long it takes for a jet plane to stop after landing at a velocity of 101 meters/second with an acceleration of -5.1 meters/second², the equation v = v0 + at can be applied. Using this equation, the time to stop can be calculated as approximately 19.8 seconds. Additionally, the runway length of 0.80 x 10^9 μ meters (or 800 meters) must be compared to the distance the jet covers while decelerating. The distance can be calculated using the equation x = x0 + v0t + (1/2)at², which shows that the plane can indeed land on Gilligan’s Island given the runway length. Overall, the calculations confirm both the stopping time and the feasibility of landing on the specified runway.

A jet plane lands with a velocity of 101 meters/second and can accelerate at -5.1 meters/second2 when coming to a rest.

a) Once it hits the runway, how long till it stops?

b) Can this plane land on Gilligan’s Island if its runway is 0.80 x 109 μ meters long?



2. Homework Equations

v = v0 + at
x − x0 = (1/2)(v0 + v)t
x = x0 + v0t + (1/2)at^2



3. The Attempt at a Solution

I have no idea how to do this problem. I have had one physics class. Sorry guys. Your help would be great

Sorry guys... i should of labeled the title to be something like..."distance covered with changing velocity" sorry I'm new here
 

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...
