A cyclist moving on a level road at 4 m/...

A cyclist moving on a level road at 4 m/s stops pedalling and lets the wheels come to rest. The retardation of the cycle has two components: a constant 0.08 `m//s^2` due to friction in the working parts and a resistance of `0. 02v^2//m` , where `v` is speed in meters per second. What distance is traversed by the cycle before it comes to rest? (consider 1n 5=1.61).
