In fact, there are only three things I have to compare: the length of the net in the swim, the speed of MJ under the swim, and the MJ mass. Finding the mass is easy. I can only look at the standards of Zendaya Coleman, who plays MJ. I will go with 59 kilos, a comparison on a well-known historical page– may not be accurate, but in the end, the need will not be excessive.
The length of the net (hence the length of the walkway), and comparing their movement across the house. Judging by the number of windows in these homes, it looks like the internet has at least eight stories. There is no equivalent length of construction story, but let’s just go with it 4 meters per level, a total length of 32 meters.
Running is very difficult, but I do my best to get a good price. If I know the distance MJ and Spidey move (I will call them Δs) and the time it takes them to cover the distance (Δt), then I can calculate the speed.
Time is not too difficult. Looking at these changes, I am able to place the frames that display at the beginning and end. Since the trailer is written in 24 frames per second, I am able to find time from the pictures. Using this, I get a time of 0.417 seconds from the start to the lowest.
Now, if I can estimate the starting point (θ), I can get the distance from the arc length (arc length = rθ). Let’s go with the starting point of 30 degrees.
That’s all I need. Here is my calculation, using the Python program. You can edit and modify the rules and run them again if you want to try different ideas.
Using my estimates, MJ and Spidey travel about 90 miles per hour (40 meters / second), and MJ is supposed to support the same weight of 800 pounds (3,555 newtons).
Sometimes it is helpful to talk about things like this based on g, whereas 1 g is equivalent to 9.8 m / s2. One G is what you feel if you just keep quiet, not rushing.
