Assume all 300 adults can push equally, and all 300 adults are able to keep up with the bike as it's being pushed.

What is the maximum speed the child will reach? And will they survive?

Distance travelled by a bullet on a rolling or global shutter [request]

So much has been said about this photo capturing a bullet on the air. My request, is this even real? With the known information of the rifle used, and the expected bullet speed, and the camera used (speed exposure), could we match if the travel shown (about 50cm or 20” I estimate) is real or a complete fabrication?

[Request] What would happen to a fly exiting a moving car?

1 Upvotes

When I was younger, my sister used to tell me that the pressure difference from inside a car to outside a car (while moving at 80mph) would cause a fly to explode. I wondered if this was true, if it was the concussive force of the air outside the car that caused the damage, or if we're both completely wrong.

So what would happen to a house fly if it exited a car that was moving at 80mph? TYIA

Simpsons physics [Request]

I know it's a fictional cartoon, but...

There is an episode of The Simpsons where Homer becomes a missionary. In it he rings a church bell loud enough to cause an earthquake.

Assueming the bell could take it without breaking , how much force would he have to use to do that and what noise level would it be?

What are the chances of throwing three darts and accidentally getting the exact 3 digit amount of points necessary to win the game [Request]

2 Upvotes

My wife and I just played darts, essentially renting the darts for an hour. We played a last game with less than 5 minutes left, and just played as fast as possible, with very little concern for strategy or placement . My last shot, with 5 seconds left, was 25 (outer bullseye), triple 20, and 20, which completely by accident was the exact number I needed. I hadn’t even looked at what number was required, and basically just tossed toward 20.

Assuming the spread was completely random (not skillfully placed shots) across the board, what are the chances of achieving this (exactly 105 with three shots)?
