A 4.5 kg object moving in the +x direction at 5.5 m/s collideshead-on with a 2.9 kg object moving in the -x direction at 4.0 m/s.Find the final velocity of each mass for each of the followingsituations. (Take the positive direction to be +x.)
(a) The bodies stick together.
____m/s (4.5 kg mass)
____ m/s (2.9 kg mass)
(b) The collision is elastic.
____ m/s (4.5 kg mass)
_____m/s (2.9 kg mass)
(c) The 4.5 kg body is at rest after the collision.
____ m/s (4.5 kg mass)
___ m/s (2.9 kg mass)
(d) The 2.9 kg body is at rest after the collision.
____ m/s (4.5 kg mass)
______ m/s (2.9 kg mass)
(e) The 4.5 kg body has a velocity of 4.0 m/s in the -x directionafter the collision.
____ m/s (4.5 kg mass)
___ m/s(2.9 kg mass)
Are the results in (c), (d), and (e) "reasonable"? Explain
