AI Thread Summary
To prevent a plane in freefall from crashing, a significant force is required to decelerate it from its speed of 1200 km/h to a stop. The discussion highlights the mass of the plane (20,000 kg) and the person attempting to hold it (50 kg), emphasizing the substantial difference in mass. The initial approach of using the formula M x G was deemed incorrect, indicating a need for a more complex calculation involving deceleration. The importance of deceleration is stressed, as failing to do so would result in a crash at high speed. Understanding the physics of force and motion is crucial in determining the necessary force to stabilize the plane.

Homework Statement


A plane is in a freefall heading downwards and is about to crash
how much force does it require for a person to hold the plane from the nose of the plane and level it down so it does not crash.

Masses
-------
Humen 50kg
plane 20,000kg
vi: 1200 km/hr

question i want to know is how much for does it take for a person that weighs that much to stop a falling plane.

Homework Equations





The Attempt at a Solution



i tried to do M x G but apparently it is not correct.

any help would be appreciated thanks.

The plane is moving... You'll need to decelerate it from 1200kmh to 0.

the plane is falling why do i have to decelerate it?
 
Well, if you don't decelerate it before it reaches the ground, it'll crash onto the ground at 1200 kmh.
 

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...
