The space shuttle releases a satellite into a circular orbit 700 km above the Earth. How fast must the shuttle be moving (relative to Earth) when the release occurs?
PHYSICS ---HELP! -
First you must find the Force of Gravity usin5g Fg=Gm1/r^2
m1= mass of the earth: 5.9736E24
r= (radius of earth plus the radius of sattelite released)
radius of earth = 6,371,000m + 700,000m = 7,071,000
Next you must find the velocity necessary for centripetal acceleration to equal the force of gravity that you just found.
take the square root
