<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?&#160;<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>

A rocket travels in the x-direction at speed 0.7 with respect tothe earth. An experimenter on the rocket observes a collisionbetween two comets and determines that the spacetime coordinates ofthe collision are (x',t') = (2.7x10^10,160).

What is the spacetime coordinate of the collision in earth'sreference frame?
Express your answer using two significant figures.

So I'm not sure if I've calculated it wrong, I tried a few times,and got 1.44ƃĀ—10^4, -2.94ƃĀ—10^10, and -9.24ƃĀ—10^9. They were allwrong. There's another part to the question asking for the time inthe reference frame, but once I find out what I did wrong here, Ican work it out myself.

The Saturn V, developed at NASA Marshall Space Flight Center (MSFC) under the direction of Wernher Von Braun, was the largest in a family of liquid-propellant rockets that solved the problem of getting to the moon. A total of thirty-two (32) Saturns of all types were launched, not one failed. The three stage Saturn V was taller than a 36 story building and was the largest, most powerful rocket ever launched. Fully loaded with the Apollo spacecraft onboard, it had a mass of 6.8 million pounds. This was still no match; however, for the five powerful rockets that controlled the first stage with 33,560,000 newtons of thrust upwards. Using this information find the net acceleration (m/s2) of the Saturn V rocket. Assume that there is no change in mass,the rocket stays completely perpendicular, and there is no drag on the rocket. This takes place on planet earth with g=9.8 m/s^2.
