Homework Help: Laws of motion

  1. May 11, 2010 #1
    A bike starts from rest. It covers a distance of 1km from rest to rest. If the minimum time in which the bike covers the distance is 100s, the coefficient of friction between road and tyre = ?

    s = (1/2)at^2

    no idea how to go about it.

    Remember the force with which the bike accelerates is friction's.
