If outer space is 62 miles away from the earth's surface, does that mean if I drove a car straight up at 60MPH I could be in space in just a bit over an hour?

>> No.7375183

yes

"There is no firm boundary where space begins. However the Kármán line, at an altitude of 100 km (62 mi) above sea level, is conventionally used as the start of outer space in space treaties and for aerospace records keeping."

No because you have too over come earths gravity, and changes in the atmospheres density and pressure. The escape scalar is 11.2 m/s.

If you were actually going straight up at 60 MPH, and stayed rotating at the same speed as the planet, yes.

OP is just talking about how space is really not that far away

Given a magic car that can drive straight up at 60mph, yes, you could reach the recognized boundary of outer space in a little over an hour.

No. Gravity would force the petrol to the back of the fuel tank and away from the pump.

but i moved the pump to the back of the tank

>>7375446
why do you refer to gas as petrol but then in the same sentence say fuel tank. Why not say petrol tank. Or is this some weird European thing.

>> No.7375455

>>7375451
because a fuel tank could hold petrol or diesel or jet A or methane, depending on the vehicle it's fitted to. faggot.

I could get there by bicycle!

Yes, but you will immediately fall back because you need very high horizontal speed to stay in orbit

That's with no further thrust input fool. If you had a road going straight up and enough fuel you could drive into space. tbh aeroplanes could go into space if it wasn't for needing air.

IF you could drive your car straight up, then yes.

Because gas/petrol are different words for gasoline, but fuel is fuel.

I used to rubbish the space elevator idea until i saw this thread. It is clear that the problem is not gravity but needing a reaction mass. If you had a space elevator you could just push along the rope and go up a la newton's third law.
