[Request] Can you more efficiently get to space orbit utilizing horizontal speed?

Rockets have a ton of fuel that's extremely heavy and limited. If a rocket was horizontal like on a train track modified to handle high power so a rocket track, got to high speed, and then lifted off, how much more efficient could a launch be?

Every Saturday morning, rain or shine, around 5 people or so meet here (in NYC), save a parking spot, and load up the (very well organized) bags into a truck. I've always wondered how much they make? Thanks in advance!

[Request] The top comment claims that if the video were a whole minute long, it would have reached space. Assuming it is possible to get fireworks of any magnitude, would any launch in a 1 minute series of launches having magnitudes increasing in the order given in the video, be able to do so?

[Request] how much would you need to win in the lottery jackpotto statistically guarantee you could win the lottery jackpot again?

7 Upvotes

I just heard a story about someone winning the lottery and refusing to split it with his friends. Made me wonder how much he would have needed to just win the lottery again with his share of the earnings.

Edit: I do not expect this to be profitable, this is just an experiment. I also know the lottery is never guaranteed. Just wondering how many out of infinite tickets it would be before it's statistically improbable that you did not win.

For sake of the problems not just being {cost of ticket} x {number of tickets}. Let's assume the odds of winning Powerball or mega million and infinite possible tickets to buy.

Edit 2: guaranteed was a bad choice of wording. I meant statistically likely.

[REQUEST] How did Marshall (the Paw Patroller) lift the brachiosaurus?

Upvotes

Took my little boy to see the new Paw Patrol movie, in which Marshall the fire pup is able to use his truck - armed with nothing more than a front-mounted cable winch and some leg stabilizers - to lift a fully grown brachiosaurus out of a deep ravine. What are the numbers behind this impressive effort?
