Problem: Samir (who is standing at rest on the ground) starts his stopwatch at the instant that Maria flies past him in her spaceship. She continues to fly her spaceship at the same constant velocity. According to Maria, at the instant that Samir’s stopwatch reads 8.0 s, Maria’s stopwatch reads 10.0 s. According to Maria, her spaceship is 100 m long (along the direction of motion). According to Samir, the length of Maria’s spaceship isA. 64 m.B. 80 m.C. 100 m.D. 125 m.E. Not enough information is given to decide.
