Welcome to Gaia! ::

A rocket sled is launced across a salt flat at a constant acceleration of 13 m/s. After t1 seconds, it stops accelerating, and continues at the consant velocity v. after t2 seconds, the rocket has travelled 5.3*10^3 meters. The total time for the trip from start to the end of t2 was 90 seconds. Find t1, t2 and v.

Note: t2 is not 90, it is actually an interval of time that starts at t1 and ends at 90.

I'll post what I got later. If I told you now, it'd ruin the fun of the problem.

haha I'm sorry nobody took the liberty of doing this yet, keep it up, I'm sure someone will do it eventually, it just might not be when you expect it or immediately. Remember this guild isn't exactly the super fast S&T forum.
