please tell me your answer and why i got the answer

An expensive sports car of mass 900 kg is travelling at a speed of 30 ms-1 when it collides unexpectedly with a stationary industrial waste bin of mass 150 kg. The waste bin becomes lodged in the front of the car. Which of the following statements about the collision will be true? There will be no kinetic energy in the system after the collision. The collision is completely inelastic. Momentum will not be conserved during the collision. All of these are true. The velocity of the car and bin immediately after impact is closest to 4.3 ms-1 26 ms-1 771 ms-1 28 ms-1

Explanation / Answer

b) collision is completely inelastic

( momentum always remain conserved in any type of collision while some energy converted into potential energy)
