Question

A man of mass 100kg stands on a wood plank of area 4m^2. what is pressure exerted on the floor? assume the area of the human foot to be 200cm^2.(g=10ms^-2)

Answer 1

m=100kg
area=4m2
pressure=force/area
force=massxg
Therefore,
pressure=massxg/area
=100x10/4
=1000/4 =250

Answer 2

Answer:

think and answer

Explanation:

F = mg

so , F = 100 ×10

therefore * = P = F / A

1000/4

so , answer = 250
