Question

As a woman walks, her entire weight is momentarily placed on one heel of her high-heeled shoes. Calculate the pressure exerted on the floor by the heel if it has an area of 1.83 cm2 and the woman’s mass is 54 kg. Express the pressure in Pa.

Answer 1

P= 2.89 × 10 ∧6 Pascal

Step-by-step explanation:

As pressure is the amount of force exerted on unit area.

Pressure, P = F/A

F = force acting on floor

F = m*g

where m= 54 kg

g = 9.8 m/s²

F= 54 * 9.8 N

= 529.2 kg m/s²

Now, Area = A

A = 1.83 * 10∧-4 m

P = (529.2 kg m/s²)/ (1.83 * 10∧-4 m)

P= 2.89 × 10 ∧6 Pascal
