Three individuals stand with all of their weight on the heel of one foot: a man of weight 600 N and a heel area of 100 cm2, a child of weight 200 N and a heel area of 25 cm2 and woman of weight 450 N and a heel area of 2 cm2. The one exerting the least pressure on the ground is .

The man of weight 600 N with a heel area of 100 cm2

Explanation:

Pressure is defined as force per unit area. Therefore

Pressure (P) = Force(F)/Area (A)

For the man, P = 600/0.01 = 60,000 Pa

For the child, P = 200/0.0025 = 80,000 Pa

For the woman, P = 450/0.0002 = 2,250,000 Pa

Hence, the one exerting the least pressure on the ground is the man with 60,000 Pa of pressure.
