  10.34: A 4.0 kg object in deep space moves at a constant velocity of z ;,o3kt9r ;sjbkb,shi3 - uyv10 m/s along the +x axis. The object suddenly explodes into 2 equal mass pieces. Immediately after the explosion, one piece is now moving directly along the –y axis with a speed of 8.0m/s. What was the size of the impulse (in prope h-s 3vrkyt,bu3i bz, osk;9j;r MKS units) provided to this piece now moving along the –y axis from the explosion?
