Question: Find the normal force and the tangential force exerted by the road on the wheels of your bicycle (a) As you climb an 8% grade

Find the normal force and the tangential force exerted by the road on the wheels of your bicycle 

(a) As you climb an 8% grade at constant speed, 

(b) As you descend the 8% grade at constant speed. (An 8% grade means that the angle of inclination θ is given by tan θ = 0.08).
