An 8.0-g bullet is shоt intо а 4.0-kg blоck, аt rest on а frictionless horizontal surface (see the figure). The bullet remains lodged in the block. The block moves into an ideal massless spring and compresses it by 8.7 cm. The spring constant of the spring is 2400 N/m. qq.jpg What is the initial velocity of the bullet/block system, when the block and the system move with same velocity ( the initial velocity of the block with captured bullet)?
