A) A 12.0-g bullet is fired horizontally into a 113-g woodenblock that is initially at rest on a frictionless horizontalsurface and connected to a spring having spring constant 149 N/m.The bullet becomes embedded in the block. If the bullet-blocksystem compresses the spring by a maximum of 76.0 cm, what was thespeed of the bullet at impact with the block?
B)A 0.033-kg bullet is fired vertically at 238 m/s into a0.15-kg baseball that is initially at rest. How high does thecombined bullet and baseball rise after the collision, assuming thebullet embeds itself in the ball?
