Assignment:
Spacecraft A is initially 120 m from spacecraft B, moving towards each other on parallel paths. Both spacecrafts apply reverse thrust to reverse their motion after which they meet twice. Spacecraft A has initial velocity VoA= +25 m/sec and acceleration aA= -3 m/sec^2. Spacecraft B has initial velocity VoB= -30 m/sec and acceleration aB=+ 4 m/sec^2. Let A be initially at the origin, and B at 120 m.
a. Find the two times and locations where they meet.
b. On the 'x vs t' set of axes show qualitatively, the x(t) graph of each spacecraft. Include x and t coordinates of intersections and intercepts.
