Answer:
C. Third
Explanation:
it has completed just 2 1/2 orbits since its discovery
D is definitely the correct choice here.
I think a case could also be made for choice-B, but that would be a tough, complex operation.
Answer:
The speed of object B is 2 times of speed of object A.
Explanation:
Given that,
Kinetic energy of object A = 25 J
Mass of object B 
Work done = -20 J
We need to calculate the factor of the speed of the object
Suppose the final kinetic energy is same for both object.


Put the value into the formula




Hence, The speed of object B is 2 times of speed of object A.
