Object A, which has a mass m and a velocity v0, collides head-onwith object B, which has a mass 2m and a velocity 1/2v0. Followingthe collision, object B has a velocity of 1/4v0.
(a) Determine the velocity of object A after the collision.
=
(b) Is the collision elastic?
2Yes
No
If not, express the change in the kinetic energy in terms of m andv0. (Enter 0 if the collision is elastic.)
?E =
