Problem

Two objects, A and B, appear the same length when A is stationary and B is moving with speed (3/5)c along its length. In the frame of reference where B is stationary and A is moving, what is the ratio of their lengths? a) LA/LB=5/4L_A/L_B = 5/4 b) LA/LB=25/16L_A/L_B = 25/16 c) LA/LB=4/5L_A/L_B = 4/5 d) LA/LB=9/25L_A/L_B = 9/25 e) LA/LB=16/25L_A/L_B = 16/25
