(a) Check all of the following that are correct statements, where E stands for ymc². Read each statement very carefully to make sure that it is exactly correct. The definition of work is W = < FxAx, FyAy, F₂A>. The energy principle can be written Esys,f The energy principle can be written AE sys = = Esys,i + Wsurr surr The definition of work is W = FxAx + FyAy + F₂Az. The definition of work is W = |< FxAx, FyAy, F₂Az >\. The definition K = E-mc² is valid even for speeds near the speed of light. At speeds close to the speed of light, kinetic energy is approximately equal to (1/2)mv2.
