A5.5 kg object moving in the +x direction at 5.5 m/s collides head-on with a 2.8 kg object moving in the -x direction at 4.0 m/s. find the final velocity of each mass for each of the following situations. (take the positive direction to be +x.)
(a) the bodies stick together.
/s (5.5 kg mass)
/s (2.8 kg mass)
(b) the collision is elastic.
/s (5.5 kg mass)
/s (2.8 kg mass)
(c) the 5.5 kg body is at rest after the collision.
/s (5.5 kg mass)
/s (2.8 kg mass)
(d) the 2.8 kg body is at rest after the collision.
/s (5.5 kg mass)
/s (2.8 kg mass)
(e) the 5.5 kg body has a velocity of 4.0 m/s in the -x direction after the collision.
/s (5.5 kg mass)
/s(2.8 kg mass)
are the results in (c), (d), and (e) "reasonable"? explain.
