Can MJ Really Hang On Swinging Spider-Man?
Granted, there are only three things I need to estimate: the length of the swing web, MJ’s speed under the swing, and MJ’s mass. Finding the masses is the easiest. I can only see the measurements of Zendaya Coleman, who plays MJ. I’m going to have a mass of 59 pounds, an estimate on a page of biographies of celebrities—It’s not accurate, but in the end, this amount doesn’t matter.
For the length of the web (and thus the radius of the circle of motion), I compared their motion as they passed through a building. Consistent with counting the number of rows of windows in the building, it seems that the web is not less than 8 floors in length. There’s no standard length for a construction story, but we’re just together 4 meters per level, for a total web length of 32 meters.
The speed is a bit tricky, but I will do my best to get a reasonable amount. If I knew the moving distance between MJ and Spidey (I would call it that
The time is not so hard. Seeing a change, I can mark the frames showing the beginning and end of the action. Since the trailer is recorded at 24 frames per second, I can get time data from the frames. Using it, I got a time of 0.417 seconds from the start of the swing to its lowest point.
Now, if I can estimate the starting angle of the swing, (I can get the distance from the length of the arc (arc length = rθ) .Let’s go to an initial angle of 30 degrees.
That’s all I need. Here are my calculations, using a Python program. You can edit and change the values and run them again if you want to try different values.
Using my estimate, MJ and Spidey would travel almost 90 miles per hour (40 meters / second), and MJ would have to support an equivalent weight of about 800 pounds (3,555 newtons).
Sometimes it’s helpful to talk about things like this in terms of g’s, where 1 g equals 9.8 m / s2. A g is how you feel when you just sit around with no speed.
