A 4.00kg box sit atop a 10kg box on a horizontal table. Thecoefficient of kinetic friction between the two boxes and betweenthe lower box and the table is 0.600, while the coefficient ofstatic friction between these same surface is o.800. A horizontalpull to the right is exerted on the lower box, and the boxes movetogether. calculate the friction force on the upper.Pull = 150.0N
