Question

A man of mass 80 kg has one foot with area 100 cm^2. find pressure exerted by the man on ground? ( consider g=10 m/s^2.)

Answer 1

Answer:

98062.5 Pa

Step-by-step explanation:

Lying: 1309 Pa

Lying: 1309 PaStanding: 98 062.5 Pa

Explanation:

When the man is lying:

Pressure =Force / Area

Force=mg

=(80 kg⋅9.81 m/s²) = 784.8 N

When the man is standing:

Pressure=Force / Area

The same force as above because of the same weight:

Force = 784.8 N

So

P=784.8 N80×10−4m2

=98 062.5 Pa
