Question

10. A bullet of mass M₁= 0.4 Kg moving with initial velocity V_1i= 800 m/s gets embedded into a block of wood of mass M₂= 3.6 Kg that was initially at rest (V_2i=0). The block is attached to a spring having spring constant K=400 N/m. After making the inelastic collision, the bullet-block combination slides on a horizontal frictioless surface and compresses the spring.

Part A
