AI Thread Summary
The discussion revolves around calculating pressure using the formula P=F/A, where a person weighing 900 N stands on snowshoes with a total area of 2500 cm² each. The correct pressure on the snow is identified as 1800 Pa, but the initial calculations mistakenly converted area to 25 m² instead of the correct 0.25 m². The confusion stemmed from miscalculating the area in square meters, leading to an incorrect pressure value of 36 Pa. Clarification was provided on the proper conversion of area, emphasizing the importance of accurate unit conversion in pressure calculations. Understanding the correct area is crucial for arriving at the right pressure value.

pressure=force/area -- cannot arrive at correct answer!?

Homework Statement




A person of weight of 900 N is standing on snowshoes. Each snowshoe has area 2500 cm2. Find the pressure on the snow.

A. 0.18 Pa
B. 0.36 Pa
C. 1800 Pa
D. 3600 Pa


Wrong Points Earned: 0/1
Correct Answer: C
Your B

Homework Equations



P=F/a

The Attempt at a Solution



P= 900N/25m^2

and i keep getting 36. how do i get to 1800??

i understand there are 2 snow shoes, how is that relevant to finding the area? and why am i 100 off?
 
Physics news on Phys.org


1 cm = .01 m

so 2500cm^2 = 25 m^2

what am i doing wrong>
 


2500 (cm^2) = 0.25 m^2
 


well duhh, teggenspiller. thank you SO very much for clearing that up!
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
