ok i used that and i get 90 degrees when i put it in as an answer it is declined I am i still doing something wrong

400km/h= 1.1*10^-4 When i plugged it into the equation I got 3.3*10^-11 I don't think this is right because that angle is to small. Can u tell me what I am doing wrong. arctan((1.1*10^-4)^2/(9.8)(2100)

I should be able to use arctan(v^2/rg) to give me the angle when i plug the numbers in i get arctan(400^2/9.8*2100)=90 and that is not the right

i know that i need to find the horizontal lift components but I am not sure how

i do not know i tried to draw a diagram for the problem and when i worked the problem out i got a really small number

Homework Statement As your plane circles an airport, it moves in a horizontal circle of radius 2100m with a speed of 400km/h. If the lift of the airplane's wings is perpendicular to the wings, at what angle should the plane be banked so that it doesn't tend to slip sideways Homework...

ok so i would use v^2= Vo^2+2aDx That woud give me acceleration and then I would use F=ma and use the mass of driver and the acceleration calculated to find the net force

Is d = vt + (1/2)at^2 the right formula if so we do not have time

[b]1. The problem statement, A driver wearing a seatbelt decelerates at roughly the same rate as the car itself. Since modern cars have a "crumple zone" built into the front of the car, the car will decelerate over a distance of roughly 1.0 . Find the net force acting on a 70-kg driver who is...
