- Homework Statement
- On a banked race track, the smallest circular path on which cars can move has a radius of 108 m, while the largest has a radius 169 m, as the drawing illustrates (image below). The height of the outer wall is 18 m.
(a) Find the smallest speed at which cars can move on this track without relying on friction.
_____ m/s
(b) Find the largest speed at which cars can move on this track without relying on friction.
______ m/s
- Relevant Equations
- a=v^2/R
F꜀=(mv^2)/R
μg = v^2/R
Basically, I need help to continue on this question. This is what I have now:
Angle of the race track (angle of the grey part):
tan(18/(169-108)) = 0.30396
Not sure how to continue?? What am I supposed to do and find next?
Thank you in advance!
