Question

the above box of mass 47 kg is sliding down a frictionless incline that makes an angle of 34^0 with the horizontal. draw the free body diagram showing all forces.

Answer 1

The free body diagram of the forces acting on the box is shown in the image attached.

How to draw the free body diagram of the forces?

The free body diagram of the forces acting on the box consists of the following;

Weight of the box acting downwards (W)

The normal force of the incline acting upwards on the box (N)

The perpendicular component of the box's weight (mg cos34)

The parallel component of the box's weight (mg sin34)

Thus, the free body diagram of the forces acting on the box is shown in the image attached.
