Centre of Mass, Momentum and Collision · Centre of mass

Two identical bodies A and B of equal masses have initial velocities v⃗1=4i^ m/s\vec v_1 = 4\hat i\ \mathrm{m/s} and v⃗2=4j^ m/s\vec v_2 = 4\hat j\ \mathrm{m/s} respectively. The body A has acceleration a⃗1=6i^+6j^ m/s2\vec a_1 = 6\hat i + 6\hat j\ \mathrm{m/s^2} while the acceleration of the other body B is zero. The centre of mass of the two bodies moves in path.
  1. (1)circular
