What Is the Time Needed to Take Off?

AI Thread Summary
To determine the time needed for an airplane to take off, one must consider its acceleration, which is given as 5.00 m/s², and the length of the runway, which is 1800 meters. The required takeoff velocity is reached at the end of the runway. By applying the equations of linear motion, the time can be calculated easily. The discussion emphasizes the straightforward nature of the problem when using the appropriate physics formulas.

Homework Statement



To take off from the ground, an airplane must reach a sufficiently high speed. The velocity required for the takeoff, the takeoff velocity, depends on several factors, including the weight of the aircraft and the wind velocity.

A plane accelerates from rest at a constant rate of 5.00 m/s^{2} along a runway that is 1800m long. Assume that the plane reaches the required takeoff velocity at the end of the runway.

Hi there,

The solution to this one seems simple. You have a plane in a linear accelerated motion. Just apply the equations and the solution should pop by itself.

Cheers
 
Yep got it thanks!
 

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...
