A Right-Angled Construction Frame ABC,when Measured at Rest,has Dimensions as Follows

Multiple Choice

A right-angled construction frame ABC,when measured at rest,has dimensions as follows: AB = 28.00 m,AC = 10.00 m,and BC = 26.15 m.The frame is given a velocity of 0.80 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 AB measured by these observers is closest to:

A) 26.8 m
B) 27.4 m
C) 26.2 m
D) 25.7 m
E) 28.0 m
