4) A 7 gr bullet is fired into a 750 gr block of wood which is at rest on a frictionless table (Isolated System) and attached to a spring with a spring constant of 8000 N/m. The bullet has a velocity of 720 m/sec and is trapped inside the block of wood. a) What is the velocity of the block before the collision? b) What is the velocity of the block/bullet after the collision? c) What is the Amplitude of the resulting SHM?
