Question

How much pressure is applied to the

ground by a 30 kg man who is standing
on square stilts that measure 0.98 m on
each edge?

Answer 1

306.12N/m^2

Step-by-step explanation:

Mass = 30 kg

g = 9.8m/s2

F = mg

F = 30 x 9.8

F = 294N

L = 0.98m

Since the stilts is square, then the area is L^2

A = L^2

A = 0.98^2

A = 0.9604m^2

P =?

P = F/A

P = 294/0.9604

P = 306.12N/m^2

The pressure exerted by the man is 306.12N/m^2
