While moving with a velocity v1= 9.8 i - 6.9 j - 9.4 k ) m/s, m1 = 3.4 kg collides with m2 = 8 kg, which was initially at rest. After the collision, m2 is observed to move with a velocity of v2'=( -3.9 j+ 4.7 k ) m/s. Please note that here v1 and v2' are vectors (boldface) with i, j and k being unit vectors. Find the magnitude of the velocity (speed( of the center of mass after the collison. Express your answer in units of m/s using one decimal place.
