A right-angled construction frame ABC,when measured at rest,has dimensions as follows: AB = 19.00 m,AC = 10.00 m,and BC = 16.16 m.The frame is given a velocity of 0.56 c,relative to the space platform,in a direction parallel to AC.The dimensions of the moving frame are measured simultaneously by observers on the platform.In the figure,the length BC measured by these observers is closest to:
A)16 m
B)14 m
C)12 m
D)10 m
E)18 m
