Riding round and round

A motorbike starts from rest at time t=0t=0 and begins to accelerate around a circular track as shown in the figure below. Eventually, at time t=t1t=t_1 the motorbike reaches the maximum velocity possible without slipping off the track. What's the minimum length in meters the motorbike must travel between t=0t=0 and t=t1t=t_1?

Details and assumptions

  • Assume that the friction coefficient everywhere on the race track is the same.
  • The motorbike wheels never slip on the track as it accelerates.
