Before impact, v B = -10 i (m/s), and v A = 15 i (m/s) They stick together after the collision. What is their combined velocity after the collision? and, if the collision takes 2ms, what is the average impulsive force experienced by B during the collision? If time: What is their combined velocity if, instead of the velocity above, A has the velocity v A = 15 i + 4 j + 2 k (m/s) before the collision?...
