What is the normal acceleration of a car?

Answers

The normal acceleration in the United States is zero to sixty time. The average rate on ordinary cars was between 3 and 4 m/s2

I went to everybody's favorite search engine to get some data to answer this question with. I can't name it, but it rhymes with Floogle. Anyway, I searched for the phrase "zero to 60" just to get an idea of what's hot.

Floogle pointed me to a website that provided this data on fast cars:

#1). 2016 AMZ Grimsel Electric Race Car0-60 mph 1.5 sec

#2). 2014 Porsche 918 Spyder0-60 mph 2.3 sec

#3). 2015 Tesla Model S P90D 'Ludicrous Speed' Upgrade0-60 mph 2.6 sec

And my favorite, because I own one:

#4). 2000 Dodge Intrepid ES 0-60 mph 8.4 sec

Here are the accelerations for the zero-to-60 times listed for these 4 cars:

#1). 17.88 m/s² (1.82 G's)
#2). 11.66 m/s² (1.19 G's)
#3). 10.32 m/s² (1.05 G's)
#4). 3.19 m/s² (0.33 of a G)

That's what these "fast cars" will do, on the track,
with their pedals mashed to the metal.

"Normal" accelerations are all less than these.

Apply why does a box on the seat of a car slide around on the seat when the car speeds up slows down or turns a corner?

Answers

Answer:

This is because of the first Newton's law:

If an object is at rest or at moving with constant velocity, it will remain doing that untill a force is applied on the object.

Now, if the car is still, and then it speeds, the box will want to keep the movement that it was doing before, so it will slide in the seat until the box gets the same speed as the car (this can happen when the box hits the back of the seat, and the back of the seat "pushes" the box)

Now, the same happens when the car stops, now the box has a velocity and when the car stops the box will keep moving forward, because there is no force that stops the box.

Because there is pressure that shifts the box

how far away is all 9 planets from the sun

Answers

I'll provide the average distance for each since the orbit of each of the planets is not a perfect circle. The distance varies (M= Miles)

Mercury= 36,000,000 M
Venus= 67,200,000 M
Earth= 93,000,000 M
Mars= 141,600,000 M
Jupiter= 483,600,000 M
Saturn = 888,200,000 M
Uranus = 1,789,500,000 M
Neptune = 2,798,650,000
Pluto = 3,674,500,000 M

The distance of each planet from the sun varies from each other. Mercury is 58 kilometres away, Venus is 108 kilometres away while the earth is 150 kilometres away from the sun. Mars is 228 kilometres away from the sun while Jupiter is 778 kilometres away and Saturn is 1430 kilometres away from the sun. Uranus is 2870 kilometres away from the sun, while Neptune and Pluto are 4,500 kilometres and 5,910 kilometres away from the sun.
