A block of mass m sits at rest on a rough inclined ramp that makes an angle 0 with the horizontal. What must be true about normal force F on the block due to the ramp? 0 F = mg sin(9) 'C' F > my C F > my cos(0) C F > mg sin(6) C F = mg (335(0) A 3.0-kg and a 5.0-kg box rest side-by-side on a smooth, level floor. A horizontal force of 32 N is applied to the 5.0-kg box pushing it against the 3.0-kg box, and, as a result, both boxes slide along the floor. How hard do the two boxes push against each other? O ON O 32 N O 24 N 20 N O 12 N
