Which of the following is true when an object of mass m moving on ahorizontal frictionless surface hits and sticks to an object ofmass M > m, which is initially at rest on the surface?
The collision is elastic.
All of the initial kinetic energy of the less-massive object islost.
The momentum of the objects that are stuck together has a smallermagnitude than the initial momentum of the less massiveobject.
The speed of the objects that are stuck together will be less thanthe initial speed of the less-massive object.
The direction of motion of the objects that are stuck togetherdepends on whether the hit is a head on collision.
