I've tried that it doesn't work. The question is asking me how many joules does it take to move the satellite from 310 km above the surface of Earth to 600 km. When i tried the equation you offered I'm neglecting the Earth's radius and mass which affects the gravitational pull

Homework Statement A sled starts from rest at the top of the frictionless, hemispherical hill. What is the equation to calculate the sleds speed at angle (theta) Homework Equations The Attempt at a Solution I need to figure out the equation. I'm given theta and the radius. I...

which mass are you referring too? Earth or the satellite?

Sorry about that? How much energy is required to boost it to the new orbit?

Homework Statement The space shuttle is in a 300 km-high circular orbit. It needs to reach a 610 km-high circular orbit to catch the Hubble Space Telescope for repairs. The shuttle's mass is 7.00×10^4 kg. Homework Equations ½(-G(M-earth)(M-telescope))(1/r2 –1/r1) G=6.67*10^6 Mass of...

The question gave me that as a spring constant. in the example Which is very similar the spring constant was in N/M as opposed the question which was in N/M^3

How do you convert 4.10x10^4 N/M^3 to N/M or is it the same thing?

Need help please! Homework Statement Sam, whose mass is 75 kg, straps on his skis and starts down a 50-m-high, 20 degrees frictionless slope. A strong headwind exerts a horizontal force of 200 N on him as he skies. Find Sam's speed at the bottom using work and energy. Find Sam's speed...
