A 1.57 kg mass is sliding across a horizontal surface an initial velocity of 12.9 m/s i.  If the object then comes to a stop over a time of 4.23 seconds, what must the coefficient of kinetic be? Assume that only friction, the normal force, and the force due to gravity are acting on the mass. Enter a number rounded to 3 decimal places.
