When relating the linear momentum and total energy of an object with speed v = 0.8c, which of the following changes would increase the energy by the greatest amount? Assume that it is possible to change the mass of the object

A. increase the momentum of the object to 2p while keeping the mass constant.
B. increase the mass of the object to 2m while keeping the momentum constant.
C. imagine the speed of light to change to 82% of its present value (the object is still at initial speed v).
D. increase the momentum of the object to 2p while keeping the velocity constant.
E. increase the speed of the object to 0.95c.


D.
This statement doubles the mass of the object, which is squared in both terms of the energy to momentum relation. This answer increases the energy by the greatest amount compared to the other answers, primarily because mass-energy is so great
