A 9 kg space rock has velocity vector v = 19 i (m/s). It collides with a second 15 kg space rock, which is initially at rest. The second rock is then observed to fly away with a speed of 5 m/s in a direction that is 31 degrees below the horizontal. Calculate the final speed of the first space rock, in m/s
