Question

wh 75-kg human total footprint is 0.05 m2 the hum is wearing boots. Suppose you want to walk on snow that can at most support an extra 3 kPa; what should the total snowshoe area be? 1.5

Answer 1

A total = 0.04 m²

Step-by-step explanation:

given data

mass = 75 kg

area = 0.05 m²

pressure = 3 kPa

solution

pressure when human walking on ground

p =
`(mg)/(A)` .................1

p =
`(75* 9.81)/(0.05)`

p = 14.715 kPa

and

when walk on snow got extra pressure

P total = p + p (extra) ................2

P total = 14.715 + 3 = 17.715 kPa

and

total pressure is also

p total =
`(mg)/(A)`

A total =
`(75* 9.81)/(17.715)`

A total = 0.04 m²
