Homework Statement An aircraft has to make an emergancey landing on a runway without landing gear , if the aircraft lands at 40 m\s-1 and μ is 0.5 , How far the aircraft slides before it comes to rest ? Homework Equations X=2 μ g \ v2 The Attempt at a Solution 2 x 0.5 \...

f = mu F f = 0.4 x 245.25 f = 98.1 N Answer is Maximum frictional force is 98.1 N ?

My approch to solve now is : to get the max friction I'll use this equation : f = mu F f : max friction mu : coefficient of friction F : Normal force , What I have in the Question Is the mass 25kg and the mu 0.4 , and as it is laying on a level floor I got g 9.81 m\s , So to apply the...

I know that friction is the force that is acting against motion What I understood is, the term frictional force means basically the amount of resistance that the friction can demonstrate against a body's motion acted upon by an opposite force to prevent it or slow it down .

First of all I would like to clearify that I am in a programme that gives physics questions with littile previous learning and relies on individual determenation and efforts to deliver answers " Self learning " , " Info Hunt " In the time most of you were learning science I was busy learning...

Answer - No it’s not in a state of static equilibrium, In order for a body to be in static equilibrium The vector sum of the forces and torques should be zero Moments: Moment = force × distance Clockwise= 75N × 1.25m = 93.75 Nm . Anticlockwise= 50N × 1.3m = 65 Nm. Total moments=...

What is your point ?

is it force x given distance ? in the question it would be 75 N X 1.25 m ?

I don't get these symbols ? more HELP please Please consider that I know so little, Teach me like a kid

Homework Statement If a body is acted upon by clockwise moments of 75 N at 1.25 m And anticlockwise moments of 50 N at 1.3 m , Is it in a state of static equilibrium ? If not what is required to achieve a state of static equilibrium ? Homework Equations sum of all forces on all...

I feel that this thread is pointless is it possible to delete it . \ :

Ok , Thanks I found the answer Equation : Used with liquid columns of constant density or at a depth within a substance (example: pressure at 20 km depth in the Earth). p = Height x density x gravity where: P is Pressure g is gravity at the surface of overlaying material ρ is density of...

I'm totally clueless what is the logic behind this and what is the correct method to solve
