Question

find the pressure exerted on the floor by the foot of a man ( standing on one foot) if the mass of the man is 80kg and the area of his shoe in contact with the floor is 400cm^2

Answer 1

Answer:Cora is creating a rectangular prism. The base of her prism is shown below. She plans to have a height of 888 cubes

Explanation:

Answer 2

Answer:20,000 Pa

Explanation: w=mg so we do 80x10=800N to find the force

and turn the 400cm to m to find the area which will give us 0.04m

P=F over A

force: 800 area: 0.04

800 over 0.04=20,000 Pa/N/m2

if they asked about the pressure exerted on the floor by both feet we do:

P= 800 over 2x0.04 which will give us 10,000

the reason why the value decreased when the man is standing on both feet is because as pressure decreases area increases
