Question of the Day

[talisman]

Is this one going to go 1000 replies too?

[scootro]

yes you are going 60.44704 m / s

[quikag]

Reason I ask is yesterday I was driving a rental Caddy and while driving the road, I realized the seat was a little far back, so I moved it forward just a few inches and for a split second, it felt like I was hauling a**. So, the question popped into my head.

I think your unit conversion is a little off

That was acceleration, genius.

He probably unknowingly stepped on the gas as he was repositioning the seat.

To add to that question: if you are driving down the highway and throw a ball straight up in the air, how fast do you have to be going for the ball to knock the shit out of your whiney ass kid in the back seat?

You would need to be in something capable of providing a ton of instantaneous acceleration (think top fuel dragster). Once the ball is in the air you would stab the throttle. Since the ball is in the air it's velocity would be the same as the car the moment you let go of it. In order for the ball to fly backwards the vehicle's velocity would have to increase a whole hell of a lot very quickly before the ball descends. In other words, you would need to accelerate the child to hit the ball.

Also, if the child throws the ball up and you hit the brakes very hard, the car slows down but the ball in the air does not and hits you in the head.

( Same principal that causes loose things in a car to become projectiles when in a collision. The car's momentum has stopped but everything else that is not connected is still traveling at that speed).

.....Physics......

Whats yours?

60 mph doesn't quite convert to your m/s units

[HarrisonTX]

My physics teacher will love to explain this on Monday at 10am.

If you were at 60MPH, your acceleration would be zero. Moving the seat, you would obviously be accelerating, IMO. I'll ask.

Did you arrive at your destination any sooner?

Ok...so what if your driving a car at 100mph and you plow head on into a concrete barricade and get launched from the seat, thru the windshield and fly over the hood of the car? Compared to the car you just briefly vacated....are you accelerating?

i would say yes...but I have little principle behind it. You would essentially be slingshotted out of the car as opposed to simply jumping out all willynilly like on the side of the highway at 100 mph
