The figure shows a right-angled construction frame ABC.When measured at rest,it has dimensions as follows: AB = 18.9 m,AC = 10.0 m,and BC = 16.0 m.This frame is now given a new velocity of 0.420c,relative to Earth,in a direction parallel to AC.How long is part BC of this frame with the new velocity as measured by Earth-based engineers?
A)16.0 m
B)14.0 m
C)12.0 m
D)10.0 m
E)18.0 m
