The reason you do not feel the Earth spinning is that it is angular velocity that makes you feel spinning.

If you spin like an ice dancer, you will get dizzy very quickly. You are rotating in a second or less. yet not one part of your body is moving at more than a few miles per hour.

Nobody feels frictionless motion at constant speed in a straight line, even at a million miles per hour. But when turning, you are constantly changing direction. It is the rate of change of direction that you feel.

The Earth is so big that from minute to minute you are travelling in a straighter line than you could draw with a ruler.

The Earth only turns once in 24 hours, whereas the skater turns once in a fraction of a second.

Drive around a small traffic island at 50mph and you will be thrown all over the place. Drive 50 mph around one of those big city loops they have in the USA and you won't feel a thing.

It is as simple as that.

Without a remainder. I also do not want the number to be checked by dividing it by 7 or 11. I want another solution.

Its a pendulum based desktop accessory, its usually 3-4 small metall balls hung by strings.
They are pendulum based but not single pendulum, they transfer force from one side to other side pendulum, and they bounce back and forth.
You see them in movies and its a lil hard to descirbe, but if anyone knows what im talking about please tell me what they are called and where i can buy one.

Thanx

I've tried question B & transposed the formula but then get syntax error when using the calculator

A chain hangs so that its shape is of the form:

Y=48cosh(a/48)

Determine, correct to four significant figures, using the definition
Cosh(x)=e^x + e^-x/2
a) Find the value of y when a = 25.
b) Find the value of a when y = 60.
