Answer:
4.2 x 10⁵kg
Explanation:
Given parameters:
Speed of orbit = 7660m/s
Kinetic energy = 1.24 x 10¹³J
Unknown:
Mass = ?
Solution:
Kinetic energy is the energy due to the motion of a body. It is mathematically expressed as;
K.E = mv²
m is the mass
v is speed
Now insert the parameters and find the mass;
1.24 x 10¹³ = x m x 7660²
1.24 x 10¹³ = 2.93 x 10⁷m
m = = 0.42 x 10⁶kg = 4.2 x 10⁵kg

You haven't listed any choices or offered any suggested answers.
So there's no way for us to guide you to select the correct one, and
if I want to answer this question and scoop up a few points, I have to
invent an answer from scratch.
On a speed/time graph, a VERTICAL line segment represents something
that's physically impossible.
The top of the line segment is a speed that's faster than the bottom
of the segment, but the times are both the same.
A change of speed that takes no time would correspond to infinite
acceleration. That just simply sounds wrong, and it is. Can't happen.
Velocity ratio is also defined as the ratio of a distance through which any part of a machine moves, to that which the driving part moves during the same time. An object has a mechanical advantage if it exerts a force higher than the velocity ratio.
What do they do? well they do....Science!!!
