10. A bullet of mass M1= 0.4 Kg moving with initial velocity V1i= 800 m/s gets embedded into a block of wood of mass M2= 3.6 Kg that was initially at rest (V2i=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.
