Question:
A 460kg satellite is launched into a circular orbit and attains an orbital altitude of 850km above Earth's surface. Calculate the:
e) additional energy and speed required for the satellite to escape.
Attempt:
I found Ek to be 1.27*10^10 J
Thus, the total energy is -1.27*10^10 J
The binding energy is 1.27*10^10 J.
Wouldn't the additonal energy it needs be the binding energy?
The escape speed would be calculated by root of:
v(esc) = root of 2GM/r
But the answer at the back says otherwis.e... :roll:
