Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

Question

Please do help me in this physics questions please. I promise to give a good feedback and perfect score.. Please i badly need it in 1 hour from now. This is already an answered equations/problems.

All i need to know is to know if why is it kinetic energy etc. is indicated in here. And why the symbol in this particular parts is equals or plus and minus. Or a complete explanation on why this is my answer and where did i get it from.

PLease, i do hope you could help me. I promise to give a perfect score as a feedback.

I. a) F, = -k, AX
F, - -k, AX2
AX = DX = AX2
F F, +F2
%3D
so,
Kess
k, t kz
%3D
b) since
AX = DX,- NX2 j
Kest = k, tkz
C) F= F, = F AX = AX, + AXz
SO
Ax= - ( +) F
and
k + kz
