Question

A thief stole a box full of valuable articles of weight W and while carrying it on his back, he jumped down a wall of height ‘h’ from the ground. Before he reached the ground, he experienced a load of
A.\[2W\]
B.\[W\]
C.\[\dfrac{W}{2}\]
D.zero

Answer 1

Hint: He bounced down a mass of height 'h' from ground before he arrived at the ground, he encountered a heap of zero due to freefall

Complete answer:
A free fall movement implies that the article is falling from a stature affected by gravity as it were. It falls just because of its weight and no other power. Given these conditions the article encounters a free fall.
For a proper explanation we need to have an idea about free body diagrams.
The free-body diagram tells about the four forces acting upon the object. Objects do not necessarily always have four forces acting upon them. There will be cases in which the number of forces depicted by a free-body diagram will be one, two, or three. There is no hard and fast rule about the number of forces that must be drawn in a free-body diagram.

The only rule for drawing free-body diagrams is to depict all the forces that exist for that object in the given situation. Thus, to construct free-body diagrams, it is extremely important to know various types of forces. If given a description of a physical situation, begin by using your understanding of the force types to identify which forces are present. Then determine the direction in which each force is acting. Finally, draw a box and add arrows for each existing force in the appropriate direction; label each force arrow according to its type.
It is seen that in a free fall: -
Free-falling items don't experience air opposition.
All free-falling items (on Earth) quicken downwards at a pace of \[9.8m/s\]

The correct answer is D.

Note:
You are in free fall at whatever point there is no typical power or some other vertical power to hold you up and keep you from moving downwards. At the point when you are in free fall, you can be either quickening or falling at a steady rate (when you've arrived at max speed)
