Make the free-body diagram of the following scenario

A 30Kh desk sits on the floor. Draw a free body diagram and determine the normal force on the desk.

Consider a large textbook with mass m = 6 lb = 2.72 kg at rest sitting on a wooden table. (a.)  Draw a free-body diagram for this stationary textbook. Make sure to include all the forces acting on the textbook, and clearly indicate in your diagram the net force (To be clear about it, I’m just looking for an algebraic expression of either F⃗net = m⃗a or F⃗net = 0 to appear in the diagram. I’m not looking for a number here). Also make sure to include a net force vector in your diagram (if F⃗net ̸= 0). (b.)  Now, suppose one side of this table is lifted up with a pulley and fixed in place so that the table effectively acts like/becomes an inclined plane (that is, a ramp). The angle of the incline, measured from the horizontal, is measured to be 30◦. Assume the table is NOT frictionless. Take the coefficients of static and kinetic friction between the book and table to be μs = 0.4 and μk = 0.2, respectively. Assume that this angle is large enough such that the book overcomes static…

B of mass Car A of mass m is driving with a speed 2v on a road with radius of curvature R. Car 2m is driving with a speed v on the same road. Assume that the only force in the normal direction is the force of friction. By what factor does the required force of friction vary from car A to car B so that the cars do ot slide out?

What is the correct free body diagram for the system and what is the rank of the forces from largest to smallest?

A rocket takes off from Earth's surface, accelerating straight up at 45.2m/s2. Calculate the normal force (in N) acting on an astronaut of mass 85.9kg, including his space suit. (Assume the rocket's initial motion parallel to the +y-direction. Indicate the direction with the sign of your answer.)
