You put an antimatter explosive in a 133 kg space rock, initially moving to the right at 34 m/s. This time, upon detonation, the rock fractures into three pieces. A 16 kg chunk is observed to zip off to the right (the positive direction) at 60 m/s. A 69 kg chunk is observed to zip off to the left at 59 m/s. Calculate the final velocity of the third chunk, in m/s. (Please answer to the fourth decimal place - i.e 14.3225)
