A certain young lady decides on her twenty fifth birth day that it is time to slendrize.
She weights 100 Kg. She has heard that if she moves fast enough, she will appear thinner to her
stationary friends. Then find
(i) How fast must she move to appear slendrize by a factor of 50%.
(ii) At this speed, her mass to be appeared to her stationary friends.
(iii) If she maintains her speed until the day she calls her twenty - ninth birth day then how old her
stationary friends will claim that she is according to their measurments.
