# How much time to push 80 kg cart 100 meters?

The answer will depend on the power. The work can be done in one second or a billion years!

### Why do shopping carts make so much noise?

Because the sound a cart makes is never a criteria for anyone buying a cart, and it sure should be. The noise can be deafening. If there was a place with QUIET carts, I would shop there if only to have a quiet cart. I have thought about solving this problem for a long time. I think for only $10 per cart, I could fix this problem and save the ears from that deafening noise…

### How do you increase your flexibility with ease?

Practice, practice, practice!! Practice daily, and possibly even several times a day. You have to slowly push yourself each time. Each time you are sitting in your splits, try to go down a little further, and a little further etc. It can take a LONG time to develop flexibility, but you just have to push yourself. It should hurt some but don't ever take too much. If you push yourself too much, you can possibly…

### What is my daily routine for a merchant in the medieval times?

Raise from a bed. This would have been eother on the floor or straw on a basic wood frame. Dress in clothing of the time which even a lowly merchant was very basic. Have bread and either water or ail for first meal. Then if a street merchant you would load a hand cart and push it as much as 3 miles to a site and be out in the open air in all weather…

### What is the power of a horse that hauls a 300N cart in 15 m in 240 seconds?

From the information given, we know the weight of the cart, but we don't actually know how much force the horse has to exert in order to pull the cart. Since the 300N is the only force given in the problem, let's assume that it's the force the horse has to produce. It's a minuscule force ... only about 67 pounds ... so we can take our time working on the problem, without worrying too…

### How much power is required to do 100J of work on an object when a force of 10N pushes it a distance of 10m?

A force of 10 newtons acting through a distance of 10 meters does 100 joules of work. Power is defined as the rate at which that work is done. So the power during the push is (100) divided by (the number of seconds the push lasts). Doing the job in less time indicates more power, just as you'd expect. But the total energy delivered is still 100 joules, regardless of how slowly or quickly it's…
