Question

If area of one feet of a man is 10 cm square then find the pressure exerted by man on the ground if his mass is 50 kg

Answer 1

Pressure =force/area

area=10*10^(-4)....m^2

force =500N

pressure=force/area

Answer 2

Answer:

The answer is 2450 Pascals.

Explanation:

If the area of the foot = 10cm square=0.1m square

This means that the area of both the feet  = 10 + 10 = 20 cm square=0.2m square

The mass of the man is 50 kg

Therefore,

Force= mass * acceleration due to gravity

=50*9.8m/s square

= 490 Newtons

Hence,

Pressure = Force/Area

=490/0.2

=2450 Pascals

Hence this is the answer to your question.
