Question

A 6.2 kg object moving in the +x direction at 5.3 m/s collides head-on with an 7.8 kg object moving in the −x direction at 2.5 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.
1 m/s (6.2 kg mass)
2 m/s (7.8 kg mass)
(b) The collision is elastic.
3 m/s (6.2 kg mass)
4 m/s (7.8 kg mass)
(c) The 6.2 kg body is at rest after the collision.
5 m/s (6.2 kg mass)
6 m/s (7.8 kg mass)
(d) The 7.8 kg body is at rest after the collision.
7 m/s (6.2 kg mass)
8 m/s (7.8 kg mass)
(e) The 6.2 kg body has a velocity of 4.0 m/s in the -x direction after the collision.
9 m/s (6.2 kg mass)
10 m/s(7.8 kg mass)
