Between a flat horizontal surface and the base of a 2.0 kg object, the coefficient of static friction is 0.60 and the coefficient of kinetic friction is 0.40. A horizontal force is applied to the object causing it to move at a constant velocity. Calculate the magnitude of the applied force (units: N).     NOTE: Use correct rounding and significant figures in the answer Enter numerical answer in proper standard notation, not scientific notation Do not enter units with the answer
