A target shooting game, wooden blocks are thrown into the air and shot in flight. A block of 0.8kg has a speed of 10 m/s at the top of its trajectory when it is hit by a bullet from below at an angel 60° from horizontal. The mass of the bullet is 5.0 g and its speed is 550m/s when it hits the block. The bullet is embedded in the block. What is the velocity of the block immediately after impact?
