Homework Statement
A man deals his bicycle up a 5 percent road at constant speed. Man+bicycle mass=90 kg with mass centre G. 1)Access direction of frictional forces 2) explain why frinctional force in front wheel can be neglected having a const. speed taking front wheel as FBD 3) Find normal forces
Homework Equations
Fy=0 Nf +Nr =G
Fx=0
The Attempt at a Solution
Direction is upward
Fy=0 Nf +Nr =G
Fx=0
M= 0. 0.46G= 1.08Nf.
Nf= 375.67N
Now I don't know how to show that friction in front wheel can be neglected
