![28. An observer on Earth sees rocket 1 leave Earth and travel toward Planet X at 0.5c. The
observer on Earth also sees that Planet X is stationary. An observer on Planet X sees rocket 2
leave Planet X and travel toward Earth at 0.6c. What is the speed of rocket 1 according to an
observer on rocket 2?
a) 0.65c
b) 0.70c
c) 0.75c
d) 0.85c
e) 0.80c
29. An observer on Earth sees Planet X to be stationary and also sees rocket 1 travel from Earth
toward Planet X at 0.5c. The observer on Earth also sees rocket 2 travel from Planet X to Earth at
0.5c. Rocket 2 emits a pulse of light that travels outward in all directions. According to an
observer on Rocket 1, how fast is the light pulse traveling toward them?
a) 0.5c
b) 0.6c
c) 0.8c
d) 1.5c
e) 1.0c](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0aed1095-7466-4be7-a4eb-478b31c0855d%2F72b9318d-219c-4f74-8924-e3f43ac3c3e1%2Fj3zctm6_processed.png&w=3840&q=75)
