AI Thread Summary
To estimate the pressure exerted by a person standing on the ground, the force is calculated using the person's weight, which is the product of mass and gravitational acceleration. The area of contact with the ground, typically the area under the feet, is needed to determine pressure using the formula F = PA. The discussion clarifies that this problem does not involve air pressure or fluid dynamics, focusing solely on the pressure exerted by the person's weight on the ground. Participants emphasize the importance of estimating the area for accurate calculations. Overall, the pressure estimation is a straightforward application of basic physics principles.

Homework Statement


What pressure does a person standing on the ground exert?

Homework Equations


The Attempt at a Solution


This has something to do with fluids, but I'm not sure what!

I think I should model the person as a cylinder and find the pressure on the person, then find what the pressure is on the ground?

I really have no idea, that was just a guess. I don't know how to find the pressure on the person either...

Can anyone please get me started?

Okay so I found this F = p*a

The force would be her weight (not her mass) and the area would be the one under her feet. Find the pressure.
 
I think I'm confused about the set up of the problem.

Force = 80 kg * 9.81 m/s^2

Area = area of top or bottom of cylinder?

then use F = area * pressure to find pressure?

So this has nothing to do with air pressure at all? Just confused because it's in with a bunch of other problems dealing with pressures from fluids, and I thought maybe air pressure contributes somehow.
 
The way I understand it, it has nothing to do with fluid. Just estimate the area under the feet of Emma (that's why the problem ask for an estimation of the pressure) and then use F = PA.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggle to understand the concept of the question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
