technician said:You have done exactly the right thing.
The area of 1 shoe = 0.25m^2
so 2 shoes = 0.5m^2 BUT IN YOUR EQUATION you have written 2 + 0.25 ! should be 2 x 0.25
This will give P = 1800Pa. I think the answer 0.18 is wrong !
The pressure on snowshoes can be determined by dividing the load (in Newtons) by the surface area of the snowshoes that come into contact with the snow. This will give the pressure in units of Newtons per square meter (N/m2).
The formula for calculating pressure is pressure = force/area. In this case, the force is 900N and the area is the surface area of the snowshoes in contact with the snow.
The surface area of snowshoes can be measured by tracing the outline of the snowshoes onto a piece of paper and then using a ruler or measuring tape to measure the length and width of the traced area. Alternatively, if the snowshoes are a regular shape (e.g. circular, rectangular), the area can be calculated using the appropriate formula.
Pressure is typically measured in units of Pascals (Pa) or Newtons per square meter (N/m2). However, other units such as pounds per square inch (psi) or atmospheres (atm) may also be used depending on the context.
Calculating pressure on snowshoes is important because it can help determine the weight distribution and potential impact on the snowpack. This information can be useful for determining the safety of using snowshoes in a particular area, as well as for understanding the ecological impact on the snow and its inhabitants.
