a 2000 KG CAR IS TRAVELING ON A BANKED CURVED ICY ROAD. THE ROAD IS BANKED AT AN ANGLE OF 12 DEGREES AND HAS A RADIUS OF CURVATURE OF 500 M. THE VELOCITY OF THE CAR NECESSARY TO TRAVEL ON THE ICY ROAD WITHOUT SLIDING IS???
PLEASE HELP, THANK YOU!

For this assume there is no friction, so the forces that matter are the forces parallel to the road surface
Which are:
Gravity downslope
m*g*sin(12)
Centripidal
cos(12)*m*v^2/r
without slippage these forces will balance
note that m divides out
g*sin(12)=cos(12)*v^2/r
v=sqrt(g*tan(12)*r)
=sqrt(9.81*tan(12)*500)
=32.3 m/s

Assuming the line is a one lane highway (including an go out ramp), if the line curves to the left, I initiate out interior the the main suitable option edge of the lane, pass in direction of the left area of the lane on the middle of the turn, and ease lower back to the the main suitable option area of the lane because of the fact the turn ends. This makes your direction as promptly as available, inflicting much less placed on on your tires, suspension and so on. additionally, shop on with the fee decrease sign, exceedingly while you're in a rollover services motor vehicle, including an SUV (suburban ussault motor vehicle)
