1. The problem statement, all variables and given/known data Consider a biker riding on level ground as shown. She wants to have the maximum forward acceleration possible, which means experiencing the maximum horizontal force without her wheels slipping. Draw the free body diagram for the bike accelerating forward. 2. Relevant equations F=ma kinetic friction is zero 3. The attempt at a solution there would be weight going down from each wheel (dependent on the balance of the rider), a Normal Force from each going up, rolling friction on the front wheel and static friction in the direction of acceleration on the rear wheel Is that correct? Would the force of static friction only be dependent on the weight the rider puts on the rear wheel?
