Two masses make a head-on (one dimensional) collision. A2 kg mass moving intially at +10 mys collides with a 4 kg mass moving initialy at -5 m/s. Ater the collision, the 2 kg mas has a velocity of-6 m/s and the 4 kg mass has a velocity of +4m/s. Which of the following best describes this collsion?a perfectly inhelastic collisionphysically impossible, Le. one or more required conservation laws are violatedan inelastic, but not perfectly inelastic, collision in which some mechanical energy is lostaperfectly elastic colisionacollsion in which linear momentum is not conserved but kinetic enhergy is conserved

In a perfectly in elastic collision the momentum and kinetic energy is always conserved

- m/s and the 4 kg mass has a velocity of 4m/s Which of the folowing best describes this collsion? mass moving intialy at +10 m/s collides with 4g mass moving initally at-5 m/s Ater the collsion, the 2 kg mass has a velscity of a perfectly inelastic collision physically impossible, Le one or more required conservation laws are violated an inelastic, but not perfectly inelastic, collsion in which some mechanical energy is lost perfectly elastic colision a collsion in which linear momentum is not conserved but kinetic energy is conserved

- m/s and the 4 kg mass has a velocity of 4m/s Which of the folowing best describes this collsion? mass moving intialy at +10 m/s collides with 4g mass moving initally at-5 m/s Ater the collsion, the 2 kg mass has a velscity of a perfectly inelastic collision physically impossible, Le one or more required conservation laws are violated an inelastic, but not perfectly inelastic, collsion in which some mechanical energy is lost perfectly elastic colision a collsion in which linear momentum is not conserved but kinetic energy is conserved
