Two powerless rockets are on a collision course. Rocket 1 is movingat 0.800c relative to Liz, an Earth observer. Rocket 2 is moving at-0.600 c relative to Liz. The two rockets are initially 2.52 x102 m apart and both are 50.0 m in length, as measuredby Liz.

a) What are their respective proper lengths?

b) What is the length of each rocket as measured by an observer inthe other rocket?

c) According to Liz, how long before the rockets collide?

d) According to rocket 1, how long before they collide?

e) According to rocket 2, how long before they collide?

f) If both crews are capable of total evacuation within 90 minutes(their own time), will there be any casualties?
