A bullet moving with an initial speed of v0 strikes and embeds itself in a block of wood which is suspended by a string, causing the bullet and block to rise to a maximum height h. Which of the following statements is true of the collision? 

(A) The initial kinetic energy of the bullet before the collision is equal to the kinetic energy of the bullet and block immediately after the collision. 

(B) The initial kinetic energy of the bullet before the collision is equal to the potential energy of the bullet and block when they reach the maximum height h. 

(C) The initial momentum of the bullet before the collision is equal to the momentum of the bullet and block at the instant they reach the maximum height h. 

(D) The initial momentum of the bullet before the collision is equal to the momentum of the bullet immediately after the collision. 

(E) The kinetic energy of the bullet and block immediately after the collision is equal to the potential energy of the bullet and block at the instant they reach the maximum height h.

Correct Option :- (E)

Explanation :-

During the inelastic collision between the bullet and the block, kinetic energy is lost. But the kinetic energy of the bullet and block immediately after the collision is transformed into potential energy at their maximum height.
