(i) Draw an extended free body diagram of a unicycle being pedaled on a gravel path (I have
included a starting point for what the unicycle looks like). Assume there is friction from the
gravel on the tire and the pedal is fixed at 90 degrees with respect to the lever arm. Also
assume as you pedal, the pedal will not hit the ground (Rpedal < Rire, the diagram is not
drawn to scale).
