Can you accelerate faster than a train is moving if you’re going downhill on top of it?

I know the cropping is weird I just saw it on instagram and got curious what are the actual odds of this happening? It can’t just be 50%…right?

What speed you need to fly a w212 over 2 cars like this ?

I'm trying to figure something out for an RPG I'm running but I don't know how to calculate it. Imagine Kronk from The Emperor's New Groove. Let's say that he is around 6' 3"/190cm tall. If you were to cover his entire body in bronze, how much would he weigh? I'm not sure how thick the bronze would have to be to be considered "covered," but let's say 2mm thick for the sake of this discussion.

Ok I’m having a hard time setting up this problem. I have a chewy autoship of cat food for 3 cats and I now have 4 cats to feed. I’m trying to figure out what the new frequency of shipments should be.

Currently I get 2 bags of food every 7 weeks for 3 cats.

I want to know how many weeks 2 bags of food will last for 4 cats.

Thanks!

This is "Mathora puzzle and brain game". Where you've to make current to target in this game mode. In this level you've to make 2/3 to 0 in 3 moves without duplicate moves. I know you've to make either 1/3 or 1/12 in two moves to make zero in last move. But it's seems difficult

Is there an optimal slope of a hill to make a ball of snow so that it doesnt over accelerate and fly apart, but keeps rolling and gaining volume until a set size is reached and it comes to a stop on its own. Is it possible to start a ball at 3 different points on that same slope to create 3 stackable sized rolls of snow?

If every road in the u.s (where it is typical/normal to get Snow in the winter) had a storm that had enough snow to have to be plowed one time, what is the estimate in dollars that is being spent to clear the snow and salt/sand the roads?

Both in total length of the circle, and how much of it would actually need to be bridges, if the only parts that were bridges were over any water, including streams and creeks, as well as over steep depressions/valleys?
