A slinky is stretched across a classroom to 9 meters. A compression travels along the slinky at a velocity of 2 m s . How long does it take to travel the entire 9m length of the classroom?
1,000 meters in 1 kilometerThe prefix "kilo" in kilometer means 1000.
1 foot = 0.3048 metres
2.75 x 100 = 275 cm
1,000 meters = 1 kilometer

A slinky is usually made of around 65-80 feet of wire, depending on the size and length of the slinky.

The original Slinky is made up of 80 feet of high-grade blue-black steel wire, coiled into a helical spring.

If a slinky is tangled or bent out of shape, you can try gently pulling and twisting it back into its original form. If the slinky is broken or stretched out, it may be difficult to repair and you might need to replace it. Regularly untangling the slinky after use can help prevent it from getting damaged.
NASA took a slinky into space on mission STS-51-F, also known as Space Shuttle Challenger mission in 1985. The slinky was used to demonstrate principles of microgravity in space.

It takes 1000 meters (not 100) to make a kilometer.
We thank you for adopting a slinky! Now that you have a slinky of your own, you can find many uses for your little friend. Traditional uses involve putting the slinky atop a high object -commonly a staircase. Place the slinky on one flat end, and then tip the top of the slinky, so the other flat end falls onto the next lowest area -in this case, the next stair step. The slinky will then begin to fall down the stairs on its own, flipping and flopping over itself as it goes. If you wish, you may sing the Slinky Song as it does so. Slinkies are also useful for stretching, and particularly loing ones can be used for clumsy games of jumprope, emulating a sine graph (wonderful for distracting physics students!), and wrapping around things. The ends of a slinky can also be used for poking things, but we ask you not to harm anyone with your slinky, for it makes the slinky sad. Remember to take good care of your slinky, lest it get tangled and very hard to unravel. We wish you years of fun with your slinky, and perhaps you'll find even more uses for it.
A slinky would have difficulty going upstairs because its movement relies on gravity and a smooth, continuous surface to travel on. The steps of the stairs disrupt the slinky's ability to maintain its shape and movement, causing it to become tangled or stuck.
