The block’s mass is 25 kg.
The man’s weight is 50 kg.
Gravitational acceleration = 10 m/s2
F = 25 x 10 = 250 N is the block’s weight.
W = 50 x 10 = 500 N is the man’s weight.
In the first example, the guy raises the block by providing a 250 N upward force (same as the weight of the block)
There will be a downward response on the floor, according to Newton’s third law of motion. The man’s actions on the floor.
= 750 N = 500 N + 250 N
The individual in the second example exerts a downward force of 25 kg wt. The response is in the upward direction, according to Newton’s third law of motion.
The man’s behaviour on the floor in this case
= 500 N – 250 N
As a result, man must adopt the 2 method.
