3. Draw FBD of rider and bike combined assuming starting from a standing start (Current velocity=0, note this does not mean acceleration=0). Mass is NOT negligible. Include all numerical values. Determine normal forces at the ground (this is not a statics problem!). mg hcg drc dfc Rs mg Rh rfl Ifl rfa Ifa Rider Loads, m is mass of bike and rider combined, mr is rider mass (Note: Right pedal is on the chain side, the pedal the right foot is on)
