Which of the following correctly describes a perfectly inelastic collision between two objects in an isolated system?
(a) The objects separate after impact, and the total kinetic energy after the collision is less than before.
(b) The objects stick together after impact, and the total kinetic energy after the collision equals the initial kinetic energy.
(c) The objects stick together after impact, and the total kinetic energy after the collision is less than before the collision.
(d) The objects stick together after impact, and the system’s momentum decreases because energy is lost to heat.
