here we have

now we can find time period as




Now the density is given as

Answer:

Explanation:
By energy conservation and work energy theorem we can say that after bullet hits the block, it will move on the rough floor and comes to rest
so here work done by frictional force = change in kinetic energy
so we know that





now by momentum conservation we have
