1)Two objects undergo a perfectly inelastic collision. Object 1 has a mass of 1.45 kg and object 2 a mass of 2.8 kg. Just prior to the collision, object 1 has a kinetic energy of 97 J and object 2 is at rest. What is the kinetic energy of this two object system just after the collision? What is the initial velocity of Object 1?
2)What is the total kinetic energy of the two cart system after the collision?
3)What is the total momentum of the two cart system after the collision?
