Answer #1

option d can not be correct as mg is not vertical.

Option e can not be correct as N is not perpendicular to surface.

Option c also can not be correct as fnet is there.fnet is resultant of the all force and not really a force.

body. In free body diagram , we have to show all the forces acting on the mat is the effect of the forces acting on the body

Normal always acts perpendicular to the surface.

Mg acts downward.

Friction tends to oppose or opposes the motion.

    1. A block with weight W = 30 N is on a flat horizontal surface. You pull to the right with a force F = 16 N. There is gravity present and the coefficient of friction is static = 0.4 and kinetic - 0.25. You are also pulling straight up with an applied force of 12 N. Now what are: The normal force N-_ the frictional force f- the net force on the block Foot and acceleration a = 2....
