Circular Motion - Frictional Forces in Circular Motion

See more videos at:

In this video, we look at how to solve for a frictional force in circular motion for a bicycle travelling around a track.

Wouldn't friction be pointing down the bank to the left?

Hi ! great video ! finally could find someone who did it. Btw which program did you use for this ?

You did it wrong, in the very end where you did 115= 60v^2/60 and cancelled out the 60s
you subbed in 60 as m which is wrong
60 N = mg
60/9.8 = m
therefore, 115 = 60v^2/60*9.8
115 = v^2/9.8
