Easy! MV^2/2= MC^2 V^2=2(C^2) V=sqrt[2(c^2)] You can figure out the rest...
UPDATE: Actually, the guy who did the above is incorrect. It's not that easy: clearly V cannot equal the square root of 2c^2, because that would mean that the velocity of the particle exceeds the speed of light...and as we all know, nothing can travel faster than the speed of light. I'm currently trying to work out the answer myself...but can't. :( A3 You have to use the definition of relativistic KE to get a reasonable answer. KE = total mass energy - rest mass energy. So when KE = restmass energy you get total mass energy = 2x restmass energy. The formulas are then; mc^2 = 2m0c^2 m = 2m0 m0/sqrt{1-(v/c)^2} = 2m0 1/{1 - (v/c)^2} = 4 v = .866c , so when the velocity is .866 the speed of light the relativistic kinetic energy will equal rest mass energy m0c^2 .
What else can I help you with?
What does an object have when moving that it doesn't at rest?
An object has kinetic energy when it is moving and not when it is at rest. When it is at rest it has potential energy.
What object has low kinetic energy?
An object at rest or moving very slowly typically has low kinetic energy. For example, a stationary rock or a snail moving slowly would have low kinetic energy.
Is energy at rest potential or kinetic energy?
Energy at rest is potential energy. It is stored energy that has the potential to be transformed into kinetic energy when an object is in motion.
When does an object have no kenetic energy?
An object has no kinetic energy when it is at rest or stationary, meaning it is not moving. Kinetic energy is the energy associated with an object in motion, so if the object is not moving, it does not possess any kinetic energy.
All objects have kinetic energy.True or False?
False. All objects do not have kinetic energy. Kinetic energy is the energy an object possesses due to its motion. Objects at rest do not have kinetic energy.
What does an object have when moving that it doesn't at rest?
An object has kinetic energy when it is moving and not when it is at rest. When it is at rest it has potential energy.
When does an object have no kinetic energy?
An object has no kinetic energy when it is at rest or not in motion. Kinetic energy is the energy an object possesses due to its motion, so when there is no motion, there is no kinetic energy present.
What object has low kinetic energy?
An object at rest or moving very slowly typically has low kinetic energy. For example, a stationary rock or a snail moving slowly would have low kinetic energy.
Is energy at rest potential or kinetic energy?
Energy at rest is potential energy. It is stored energy that has the potential to be transformed into kinetic energy when an object is in motion.
When does an object have no kenetic energy?

Definition objects at rest?
An object that has no kinetic energy, only potential energy.
All objects have kinetic energy.True or False?
False. All objects do not have kinetic energy. Kinetic energy is the energy an object possesses due to its motion. Objects at rest do not have kinetic energy.
How do ponetic and kinetic energy differ?
Potential energy is stored energy while kinetic energy is the energy of motion. When an object is at rest, it has potential energy that can be converted into kinetic energy when in motion. Potential energy is related to the position or configuration of an object, while kinetic energy is related to the object's motion.
Is kinetic energy is the energy an object has to due to its motion?
kinetic energy-energy in motion object that change from being at rest
What is the kinetic energy of a 50 newton object resting on the edge of a cliff 30 meters high before it fell?
The kinetic energy of the object when it is still at rest on the edge of the cliff is zero because it has no motion. Kinetic energy is the energy possessed by an object due to its motion, so as long as the object is stationary, it has no kinetic energy.
Energy at rest is?
the energy due to position potiential energy
An object that has NO kinetic energy must be?
An object with zero kinetic energy is at rest. However, since reference frames are relative, the calculation of kinetic energy is done with reference to an arbitrary point.
