Question 1

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?



◦ 16.0 m
◦ 12.0 m
◦ 14.0 m
◦ 10.0 m
◦ 18.0 m

Question 2

The figure shows a right-angled construction frame ABC. When measured at rest, it has dimensions as follows: AB = 26.0 m, AC = 10.0 m, and BC = 24.0 m. This frame is now given a new velocity of 0.760c, relative to Earth, in a direction parallel to AC. How long is part AC of this frame with the new velocity as measured by Earth-based engineers?



◦ 6.50 m
◦ 24.3 m
◦ 24.9 m
◦ 23.7 m
◦ 25.4 m
