Question

A girl standing upright exerts a pressure of 13600Nm^-2 on the floor .Given that the total area of contact of shoes and the floor is 0.036m². i)determine the mass of the girl .i) determine the pressure she would exert on the floor if she stood on one foot.

Answer 1

Answer:

p=13600 N/m²

A=0•036m²

F=?

F=P×A

=13600×0•036N

=489•6N

F=m×g

or,m=F÷g

or, m=489•6÷9•8=50 kg
