Thank you both very much. :)

Okay, so how do I solve it?

This is a conservation of energy question.

If it was, wouldn't work always be 0 then?

Change in kinetic energy, as I understand it.

They want the kinetic work, so the change in kinetic energy is the answer. I think.

Sorry, I still don't understand how to solve this.

Homework Statement How much work is done moving a 1500 kg spacecraft from the Earth's surface into a fixed orbit at a height of 300 km above the Earth's surface? Homework Equations Eg = -Gm1m2/r Ek = 1\2mv^2 mass of earth: 5.98 x 10^24 kg radius of earth: 6.38 x 10^6 m The...

Oh, alright, thank you!

I'm pretty sure I'm only supposed to use information provided from the question though..

Homework Statement In the Bohr model of the hydrogen atom, the electron revolves around the nucleus. If the radius of the orbit is 5.8 z 10^-11 m and the electron makes 6.6 x 10^15 r/s, find; a) the acceleration of the electron b) the magnitude of the gravitational force of attraction...

Thanks for all your help, guys. I figured out the problem. Thanks for your time and help. :)

Thank you! I'll try that! Thanks so much for your time and help

Um.. I don't know what you mean! I'm sorry, I don't know what the mini-van equation is.. Could you perhaps explain it a little more?

Homework Statement Emanual Zacchini was shot over three ferris wheels, landing in a net at the same height from which he was shot. Given his initial velocity of 27m/s [53degrees U of R] and range of 69m, find a) his maximum height reached b) the time spent in air, using two different...
