Kinetic coefficient

  1. Sep 9, 2015 #1
    1. The problem statement, all variables and given/known data
    A 4.30 kg block is pushed along a floor by a constant applied force that is horizontal and has a magnitude of 43.0 N. The figure gives the block's speed v versus time t as the block moves along an x axis on the floor. The scale of the figure's vertical axis is set by vs = 5.30 m/s. What is the coefficient of kinetic friction between the block and the floor?

    2. Relevant equations
    f=ma
    3. The attempt at a solution
    i think the acceleration is 5.3 m/s^2 but im not sure and i dont know where to go once i find the acceleration
