On the window area, what is the measurements for a typical side of a typical house and what is the measurements of a typical size window?
One way to make the estimates would be to make a sketch of a typical side of a typical house, then measure the dimensions of the side and the dimensions of the windows. Figure out the areas.
Quicker and just as good: Make your sketch. Then try to fill the rest of the wall with average-sized windows and see how many windows it takes, compared to how many you originally had in your sketch.
The equation is from problem 33 and their are 3 different equations and they want you to tell which equations can work and which one's can not.
The equations are
X= vt^2 + 2at
X= v(initial)t + .5at^2
X= v(initial)t + 2at^2
I don't know what to put in for X when I am sloving the equations using the units from 1-8.
This isn't one of the equations but here is an example:
If the equation is `ds = v0 `dt + .5 a `ds, which is not one of the equations of motion but at first glance looks OK, you check out the units of each term of the equation.
Using MKS units:
The units of `ds are meters.
The units of v0 `dt are m / sec * sec = meters.
The units of a `ds are m / sec^2 * m = m^2 / sec^2.
Since you can add unlike terms, you can't add meters to m^2 / sec^2, and the right-hand side is not dimensionally consistent.
