<p>Question- Two powerless rockets are on a collision course. The rockets are moving with speeds of 0.800c and 0.600c and are initially 2.52x10<sup>12</sup>m apart as measured by an Earth observer. Both rockets are 40.0m in length as measured by the Earth based observer.<br />A.) what are the proper length of the rockets<br />B.) what is the length of each rocket as measured by an observer on the other rocket<br />C.) According to the Earth based observer, how long before the rockets collide?<br />D.) According the rocket 1, how long do they collide?<br />E.) According to rocket 2, how long do they collide? <br /><br />This is a problem I came across in my modern physics homework. What my problem is, is that I didn't understand the parts about the two rockets colliding, therefore I didn't know how to approach this problem. Is somebody able to help guide me through the 5 steps listed above?</p>
