Some particles, like photons and gravitons, are believed to ALWAYS travel at the speed of light. Particles, or larger amounts of matter, that move at a slower speed can't be made to travel at the speed of light - according to the Special Theory of Relativity, that would require an infinite energy.

When train is travell with speed of light nd we put a mirror in front of me then what will image formed?
An object such as a train simply CANNOT travel at the speed of light. You can investigate what happens when it moves close to the speed of light.
If you were travelling faster than light could you still see an object in front of you?
You cannot travel at the speed of light. Period.
An object moves in light speed will shred its mass?
An object that normally doesn't move at light speed (so, this doesn't include photons for example) CANNOT move at the speed of light. As it approaches the speed of light, its mass will get higher and higher (and tend towards infinity); as will the energy required to continue speeding it up.
What is the fastest speed of any object in the universe?
The speed of light. 300,000 km/h, is the fastest speed of any object in the universe.
Why can satellites not attain the speed of light notwithstanding they are in absolute vacuum?
As the speed of an object approaches the speed of light, its kinetic energy approaches infinity. An object moving at the speed of light would require inifinite kinetic energy.
How much energy you would produce if you were going the speed of light?
Since no object with mass can reach the speed of light -- such an object can only approach that speed -- the question is meaningless.
Object traveling through the speed of light?
Electrons are able to travel close to speed of light.
Is the speed of light a factor in warming an object?
No.
What would happened if a household object moved one millimeter at the speed of light?
A household object cannot move at the speed of light, therefore, it is impossible to give a meaningful answer to that question. I will say, however, that if a household object moved one millimeter at anything close to the speed of light, it would have such enormous momentum that it would be impossible to slow it down without causing massive destruction. Your household, and neighborhood, would not survive.
When a light is shined onto an object the particles must temporarily stop as they hit the object before reflecting back to you to be perceived so what force accelerates the light particles?
Newtonian physics. Every action has an equal and opposite reaction - the object pushes back with the same force the light particles had. Since the speed of light cannot change without refraction, it still goes at the same speed.
The upper limit to the speed of an object with mass?
An object with mass might approach, but never reach, the speed of light.An object with mass might approach, but never reach, the speed of light.An object with mass might approach, but never reach, the speed of light.An object with mass might approach, but never reach, the speed of light.
Why use constants?
Constant is the speed of light and as the speed of light cannot change it is 'constant'
