One girl wanted to be strong like Pippi Longstocking and like her to be able to lift a horse,if not here on the Earth at least on the Moon.The weight of the horse is 240kg.

-calculate how much would be the weight of the horse on the Moon.

-what do you think-can you really lift the horse there?

Pipi had decide to prove that she can reduce the weight of the horse even here on the Earth.With what speed she needs to run on the equator in order the weight of the horse she carry to be the same as at the Moon?

The weight of the horse would be about 1/6 as much, or 40 kg. I don't remember the exact conversion, but I know its near 1/6.

Can she really life the horse there? No way? 40 kg is too much for a girl.

Also, I could be wrong, but since she'll way 1/6 as much also, why does going to the moon help? Someone with a physics background should help out here .... if you weigh less but have the same mass, what does that do to your ability to lift?

And, I don't have a great physics background, but the horse will "weigh" the same regardless of how fast she is running. Maybe there's something about weight that the faster you run the less the impact of gravity has, so weight is less.

The mass of the horse is 240 kg, no matter where the horse is. Converted to pounds, the horse weighs 528 lbs. This weight (pull of gravity) of the horse is lessened by about 1/6th, making the horse feel about 88 lbs. on the moon.

The horse is still quite heavy, and I do not think our young heroine can lift such a big horse.

H2o - that's one of the ways astronaughts train.

Don't know quite if that does it but it's my first thought and that works in trivia!

Also you said here not here on earth

You are totaly wrong,check your physics background.Have you heared for earth and moon acceleration?

You are right about the weight of the horse on the moon-40kg.
