Calculate the pressure on a man’s foot when a woman of mass 65 kg steps on his foot with her heel which has an area of 0.12m2 with all her weight.

Answer:

Pressure = force/area

= 650N/0.12m^2

= 5416.7 to 1 d.p

I got 650N by taking the gravitational field on earth to be 10N/kg.

Weight = mass x gravitational field

= 65 x 10N/kg

= 650

Answer is 5416.7 pascals (Pa)

Or

5308.3 Pa

if gravitational field was taken to be 9.8N/kg

Hope this helps!
