What %-error is there in using îmv2 for kinetic energy (instead of the more accurate expression from special relativity) of a particle if the speed is a. 0.01 c, b. 0.5 c, c. 0.99 c?

when it gains or loses electrons

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
